Car tires, like all parts in a car, have their own specific resource, as a rule, with careful operation and normal quality, tires last from 4 to 6 years. But often there is intensive premature wear of tires, as motorists say, it eats rubber. Tires can “eat up” in different places of the tread, wheel wear occurs both on the front and rear axles.

It is not easy to say unequivocally why tires wear quickly, sometimes it is difficult even for experienced drivers to find the cause. But in many cases, the “zhor” of tires indicates existing malfunctions in the car that need to be fixed.

The main reasons why he eats rubber from the outside

Rubber on a car can be eaten both from the outside of the tread and from the inside, the main causes of external intensive wear:

• incorrect toe-in adjustment (wheels are tilted more than expected in different directions);
• the presence of backlash in the steering rods and tips;
• factory defect of tires;
• high speed when cornering;
• insufficient tire pressure.

As a rule, when the outer part of the tread is intensively eaten, the rubber makes an unpleasant squeak when cornering. On many passenger cars, the tires on the front axle wear out first of all, since the “zhor” occurs during braking, and the load mainly falls on the front disc brakes.

Also, a hernia may appear on the outer side wall of the rubber, which occurs as a result of a side impact, falling into a hole in the road. It should be noted that the bulge on the tire does not always appear immediately, a hernia can be detected only after a week or even later. Cracks from the outer part of the tire most often appear for two reasons:

• the car has been operated for a long time with low tire pressure;
• the tire has exhausted its resource, it is time to change it to a new one.

Another option is uneven wear of the outer part of the tread along the radius, a kind of bumps appear on it. The main reason for the occurrence of such a defect is a faulty suspension, punched shock absorbers are primarily to blame for this.

Eats rubber from the inside on VAZ-2101-07 cars

On any car, the tread on those wheels that are driving wears out first of all, therefore, on all rear-wheel drive VAZs, the rubber on the rear axle is eaten more intensively. The main reasons for the intensive wear of tires on the "Classic":

• the geometry of the body is broken (usually after a blow to the rear);
• bent "stocking" (body) of the rear axle;
• out of order jet thrust(bent, broken bushings);
• curves wheel disks;
• wheel alignment not adjusted.

Uneven wear of the tread of one of the tires on the axle can occur due to different tire pressures, for example, in one wheel 1.5 Atmospheres, in the other - 2 Atm.

The reason for the "zhora" of tires on the front axle of the VAZ is often faulty silent blocks, here the internal bushings can be displaced or broken. Also, rubber often wears out due to a blow to the wheel (getting into a pit at speed), in which case the tire on the side of the axle where the damage occurred is “eaten up” more intensively.

All the same problems with tread wear are also observed on Niva cars, since the suspension of this model is structurally almost the same as on the VAZ-Classic.

Why eats rubber from the inside and the outside at the same time

It often happens that the rubber is “eaten up” on both sides of the tread at once, as a rule, in this case, the car does not lead to the side, it drives straight. If this happens, the low pressure in the wheels is most often “to blame”, when the tread pattern is worn only in the middle - the car is constantly operated with tire pressure above normal.

Another option is one front wheel The inner part of the tread is “eaten up”, on the other - the outer one. In this case, most often the cause of the defect is incorrect wheel alignment, but on some auto models, the wheel alignment is not adjustable, for example, on Gazelle cars. On cars manufactured by GAZ, the collapse is exhibited from the factory, and factory defects are not excluded here. Another "culprit" of the malfunction is a worn hub bearing, its diagnosis should be carried out with the wheel hanging.

Causes of premature wear of the tire tread due to the fault of the driver

As we have already figured out, intensive tread wear is most often the result of malfunctions in the car, but the car owner himself is not so rarely to blame for the rapid failure of tires, and here are the main reasons:

• car operation on bad roads;
• aggressive driving style (driving with a sharp start and braking, a long trip along the highway at high speed);
• irregular maintenance, untimely repairs.

If tires wear out quickly, and obvious technical problems no, the driver should think about whether he is using his car correctly, maybe he should change his driving style, regularly monitor the technical condition of the car.

Why You Should Pay Attention to Tire Wear When Buying a Used Car

If you buy a used car, it is important to pay attention to the condition of the tires during the inspection, they can say a lot (of course, if the tires are not new). As mentioned earlier, uneven tire wear can mainly be caused by the following reasons:

1. Tire pressure incorrectly adjusted.
2. Wheel alignment angles set incorrectly.
3. There are malfunctions in the suspension - there are backlashes in the steering rods / tips, silent blocks are worn out, levers are bent, shock absorbers need to be replaced, and so on.
4. The rims are deformed, an imbalance occurs.
5. The geometry of the body is broken.

If it is quite simple to deal with the first four points, and the cause of the malfunction can be eliminated, then everything is more complicated with a violation of the geometry, it can be violated as a result of a serious accident, and it may not be possible to fix something in this case. Therefore, before buying a car with unevenly worn tires, you should ask the real owner to diagnose the car at a service station, and only after making sure that the body is in good condition, carry out a sale and purchase transaction.

Importance of proper tire pressure

Tires are inflated to a certain pressure so that the car can ride smoothly on the road and support its weight. If the pressure is set incorrectly, fuel consumption increases, tires wear out ahead of time, the car is less controlled and slows down.

The statement that it is necessary to inflate tire pressure of 2 atm on any passenger car is incorrect, for each car the manufacturer sets its own parameters, usually they are indicated on the central body rack of the car from the driver's side, and information can also be marked on the gas tank flap from the inside.

When measuring with a pressure gauge, it is important to take into account that tire pressure rises in heat, so you need to inflate the wheels in accordance with the season and the temperature at which the car is operated. And measurements must be made at least once every three months, and before each trip, the condition of the tires should be inspected.

True reason

For your information. Not all machines have the ability to adjust all three wheel angles. In the presence of defects and the absence necessary adjustments the cause should be sought in non-original and worn suspension components (silent blocks, etc. bushings). You should not discount the factory defects of tires or incorrect adjustment of the levers of the chassis.

Why does the car eat rubber from the outside and inside of the front wheels? Read and Eliminate

Preliminary estimate

When the first signs of wear appear, the malfunction should be repaired as soon as possible. Most of the reasons require professional equipment. But, the initial diagnosis can be made independently. To do this, you will need to leave on a flat and empty road. Start the car at a speed of 30 km / h, then drop the steering wheel for a few seconds.

If the car does not deviate from a straight line, then the problem is in the tires. With a sharp departure to the side, the cause is in the angles of the wheels, suspension breakdowns, steering malfunctions. Often these problems are accompanied by various knocks.

Tire pressure. When the pressure in one of the wheels decreases, a high load falls on it. Because of this, the wear of this tire increases. When the first signs of wear appear on the tires, you should first check the pressure in the wheels. You can do this at any tire shop or gas station. But, you just need to take into account that modern pressure gauges do not give one hundred percent accuracy of measurements. Therefore, it is advisable to carry out a test using 2 pressure gauges. This will increase the measurement accuracy.

How to determine the cause of rapid tire wear by the condition of the tire?

Few motorists take tire wear seriously. When the "rubber" loses its grip, it is customary to change it, but it is not so easy to determine the exact replacement cycle. Even by maintaining the correct pressure in a car's tires throughout their life, they can wear out much faster than their manufacturer predicts. This is due to the fact that the car has certain malfunctions that lead to early wear of the rubber tread.

From the wear pattern of a car tire, you can find out what specific malfunction is in the engine, suspension or other units. After its elimination, the rubber will serve much longer, and the car will work in the right mode.

Severe wear on the inside or outside of the "rubber"

The most common problem among motorists is one-sided tire wear. The "rubber" may wear out more on the inside or outside, and after a while it will become unusable for road use. Such a problem diagnoses for the driver the fact that the wheel alignment was incorrectly performed on his car.

If the camber is set incorrectly and the upper part of the wheel is offset from the center of the car or towards the center of the car by several degrees, tire wear on one side will increase. In some situations, a deviation from zero camber is necessary for the driver, for example, if he is racing. By setting the negative camber, it is possible to improve the contact patch of the tire with the road surface, and the car enters corners better.

In urban conditions, cars must be set to zero camber, otherwise there will be problems with directional stability, and even driving on a straight road will become unstable. To solve the problem with one-sided internal or external tire wear, it is necessary to carry out a wheel alignment of the car.

Increased wear on the outside and inside of the tire

When protector car tire wears out a lot at the edges, but at the same time remains intact in the center, this clearly indicates problems with pressure in the “rubber” during the operation of the car. When the tire pressure is low, the inside of the tire does not adhere tightly to the road surface. This leads not only to increased tire wear on both sides, but also to increased fuel consumption, braking distances and handling problems.

Driving with low tire pressure is dangerous for both the driver and other road users. If you regularly maintain tire pressure at the same level, but still have similar wear, we advise you to check in the reference information for the car whether you have chosen the correct tire pressure. It is also recommended to change the car tire pump, which may show incorrect results.

Tire dents

Even the rubber surface of tires can be coated small dents, which change the shape of the tire, and make it unusable. Along the edges of the tire, bumps and depressions form, and the reason for this is problems with the suspension.

When driving on the road, the car constantly bounces and falls, and the suspension must absorb the impact of the tires on the roadway so that they do not appear indentations. If there are suspension problems or undercarriage, cushioning impacts on the roadway may not be sufficient.

Spend complete diagnostics not every driver will be able to independently manage the suspension and chassis of the car. That is why in such a situation it is better to contact a specialist or try to replace the shock absorbers. In most cases, they are to blame for the appearance of dents on the tires.

Long-term diagonal denting and severe tread wear

This problem is relevant for the rear axle front wheel drive car. Most often it occurs when a car it is operated in cargo mode, that is, it often carries loads for which it is not designed. Also, taxi drivers can often observe a similar problem.

If the car is not used as a means for the constant transportation of heavy loads, but at the same time it has a similar problem, the reason for this is incorrect wheel alignment. As a result, before installing new rubber on the car, it is necessary to check the wheel alignment and set it to zero.

Excessive tread wear in the middle of the tire

If the tread is almost completely worn out in the middle, but such serious wear is not noticed at the edges, then the problem is driving on roads with high tire pressure. Once again, check whether you really inflate the tire to the value recommended by the manufacturer of your car model.

Some experienced drivers claim that when driving on an overinflated tire, gas is consumed less, and this is true. This is due to the fact that the car loses good grip, and all of its mass is shifted to the middle of the tire, pressing it to the roadway. Such savings in gasoline will result in the need for frequent replacement of tires due to their rapid wear.

It is worth noting that during the cold season, tire pressure may decrease due to weather factors. If you go on a trip on "ice" tires, then after some time after the start of movement, the air in the tires will begin to heat up seriously, and this can lead to an excess of the pressure recommended by the car manufacturer. As a result, the driver will get poor traction and tire wear in the middle.

To avoid problems with tire inflation when accelerating the car in the cold season, you should check that the tire pressure is within the recommended value before each trip.

tire cracks

Another problem that high or low tire pressure can cause is cracking. A tire hitting a curb or a pit is a stressful condition for a tire that it can tolerate without damage at ideal pressure. If longitudinal cracks appear on the sidewall of the tire, it means that it has been used for a long time with insufficient pressure.

Also, small cracks may appear on the tire, and it can be said from them that the life of the rubber has come to an end. In such tires, the chemical decomposition of elements begins, which allow it to maintain its properties. It follows from this that the operation of such tires is prohibited.

Hernia on a tire

When a tire with high pressure hits a hard surface, a hernia can form inside it. This is due to damage to the inner layer of rubber, and it is not immediately possible to notice the appearance of a hernia. After a week or two or even more, the hernia will manifest itself as a bulge on one of the side edges of the tire.

Caution: It is extremely dangerous to drive a vehicle with a herniated tire. If such a problem occurs, it is immediately recommended to change the tire to a new one.

Extreme tread blocks received convex wear

Diagnosing such a problem is the most difficult, since it is not visually visible. To determine the presence of convex wear on the side edges of the tread, you need to run your finger over them. You can feel that the low edges of the tread block are worn out in a rounded shape, while the high edges, on the contrary, are pointed.

If a similar problem manifested itself on the car, it is necessary to check the wheel bearings and ball joints. It is worth noting that the outer tread blocks may wear out on one tire, while the rest will be fine.

The leading edge of the tread is heavily worn

One of the most common problems is wear on the leading edge of the tread. The main problem is that most drivers believe that tires should wear out in this way during operation, but this is not the case. This wear indicates that the vehicle has some suspension problems. Most likely we are talking about a malfunction of ball bearings or silent blocks.

Diagnosis of such a problem is possible only "by touch". To do this, you need to run your hand along the edges of the tread teeth. If some of the teeth are sharper than others, then there is a problem.

"Bald spots" on the tire

If there are separate zones on a car tire that are worn out more than the rest, they are usually called “bald spots” or spots. Most often, such spots appear on the cars of drivers who like to accelerate and brake sharply. In case of rare (including emergency) braking, if the car does not have ABS system, the wheels lock up and the vehicle slips on the tire a section of the roadway. Sliding leads to an increase in the temperature of the tire and its instantaneous wear.

In addition, spots on the tires of a car can appear if it is idle for a long time. When parked for a long time, a separate section of the tire bears the entire weight of the car. Due to its structure, it can deform over time.

TOP 5 reasons why you eat rubber

Automobile rubber, like any thing, has its own specific resource and strength threshold. Therefore, it is not surprising that with intensive use of the car, rubber wears out quickly. Wear can be observed on any axle and side of the car, where there is any malfunction or violation. The normal life of tires is within 4-6 years, taking into account if the rubber has been used carefully and accurately throughout this period.

Today we will find out for what reasons rubber can be eaten? Here are 5 of the most common reasons.

1. The collapse of convergence.

Eating rubber can occur due to the uneven location of the wheels in relation to the body. The camber is responsible for the position of the wheel along the vertical axis, while the convergence is responsible for the placement of the wheels when entering a turn.

Why, with incorrect indicators, after a while it can begin to eat up rubber from all sides and on different wheels. For example, if wear is observed on the inside, then too much inclination has been made. This position of the wheels is called negative camber. Accordingly, if the outer side is worn, then this is a positive collapse. So the wheels are tilted in different directions. Also, if the camber is incorrect, the rubber can eat up on one wheel from the inside, on the other from the outside.

Why do the camber settings go astray? There are several reasons:

Not timely control, long operation of the car on bad roads.

Hitting curbs, potholes, and other potholes and bumps.

After repair of the suspension, replacement of levers, silent blocks, steering tips, rods, etc.

Deterioration of suspension elements.

Tie rods are bent, there is play in the bushings, etc.

Bent bridges, the hull itself.

2. Low or high pressure tires.

When operating wheels with low pressure, accelerated wear begins on that part of the tire that breaks and flexes. With low pressure:

The rim begins to press on the surface of the tire;

The tire structure flexes at the edges.

That is, it is clear that with insufficient pressure, the side part often wears out, both from the inside and from the outside. With excess pressure, respectively, wear will be observed in the middle of the tire.

3. Uneven pressure.

A common reason for those motorists who do not monitor the car and tire pressure in principle. The uneven pressure of the wheels on the same axle almost always leads to wear on one side or the other, depending on the operating conditions. For example, on the right front wheel the pressure is 1.5 Ba, on the opposite wheel it is already 2.0 Ba. That is, there is a difference, which means that uneven wear occurs. In such cases, often the car begins to "drive" in one of the directions, as a rule, where there is less pressure. There is also a “zhor” of rubber.

4. Incorrect storage of tires in summer or winter season. It is known that it is impossible to store tires one on top of the other, especially if they are stored with dressed disks. Under the pressure of the weight, the tires sag to one side. After a long “laying” in this position, the tires in most cases can no longer be restored.

The correct method of storing tires involves mounting the wheels on edge, that is, as the wheels are on the car, so you need to store them. Periodically scrolling so as not to get stuck. Or better yet, hang it up. If the tires are dressed on disks, then you can lay them flat.

5. Aging, manufacturing defects.

It is rare now that a tire is used beyond its expiration date, rubber tends to wear out sooner from overuse. But, still, do not discard this reason. Check for cracks, pores on the rubber. Violation of tightness, all this directly affects the operation of tires. If the rubber is damaged, moisture gets inside, which eventually leads to the destruction of the metal shell of the tire, the so-called cord.

According to the standards of manufacturers, the operation of tires whose age exceeds ten years is prohibited.

Of course, this is not the whole list of reasons why rubber is eaten away. There are a number of other problems, but they are less common. So:

Violation of the shape of the disc, for example, after a strong blow to the curb, pit, etc.

Suspension damage and failure, such as a factory or purchased defect knuckle, levers.

Damage to the strut, for example, bent after a strong impact.

A worn hub bearing, of course, the play in this case should be strong, it will be difficult not to notice it. But, nevertheless, when checking by the elimination method, it will not be superfluous to check this node as well.

After the impact, the tire moved off the disk, changed the landing geometry. Drive on the “tavern” or remove the wheels yourself, spin it, if the tire has moved out, it will be noticeable.

Changing the geometry of the body. After a strong impact (accident) or overturning of the machine. It can only be determined with a special tool. It is not uncommon that the reason for the violation of the body geometry is that the machine is simply welded from several parts. That is, "constructor", such are common in the Far East, where it is cheaper to overtake a cut from Japan, and then, having welded it, "push" it like a normal car.

Conclusion

As a result, I would like to emphasize the importance of periodic suspension diagnostics, checking the camber, tire pressure. By the way, experts and manufacturers recommend checking the collapse on average every 3,000-5,000 km, given the road surface, perhaps more often.

During the noticed reason, it will save from premature rubber burning, and also allow, possibly, to save the health, life of the driver and passengers. Good luck on the roads.

. Eats rubber from the outside in front

Why does it eat rubber from the inside in front or from the outside on both wheels

Tires are a consumable and seasonal material. It is theoretically difficult to predict the degree of their wear depending on the mileage. Almost everything depends on rubber compound mixtures. Over the years, the average service life is about 5-6 years. This is the limit, upon reaching which the product will acquire cracks, and if they are present, there is a high risk of getting into a dangerous situation. However, the tire may lose its proper appearance much earlier.

Premature wear or eating rubber on the car from the outside in front: treatment

A common cause of short wheel change intervals is uneven tread wear. Installing a new set of tires can rarely correct the situation, since a malfunction is more often the result of incorrect machine settings and untimely care for it. Even an elementary procedure for monitoring tire pressure can prevent untimely failure of a tire industry product.

Critical adjustments

The front suspension is a complex mechanism, but amenable to adjustment. Therefore, if it eats rubber from the inside in front, it is necessary first of all to analyze its current settings. Yes, and premature wear of the outer shoulder is also a reason to inspect the relative location of the front suspension arms.

Such a chassis arrangement is designed not only to optimize the wear resistance of tires. First of all, other goals are pursued - increasing the stability of the car and ensuring easy handling. In the process of adjustment, it is customary to distinguish between three types of parameters:

• Camber - the angle between the longitudinal plane of the wheel and the vertical axis or the position of the wheels in relation to the road surface. Affects the area of ​​the contact patch with the road. Preferably a negative value.
• Convergence - the position of the tires relative to the horizontal plane. Required to compensate for the elastic movements of rubber parts when transferring traction to the wheels.
• Caster - the angle of inclination of the transverse vertical plane of the wheel relative to the vertical axis. Needed to ensure self-return of the steering wheel when exiting a turn.

Accurate Diagnosis

One-sided wear of the tread in most cases indicates the incorrect setting of the above settings. In particular, rapid wear of the outer shoulders of a tire causes increased positive camber. In this case, the top of the tire is tilted away from the center of the car. There is no universally correct adjustment - for everyone vehicle own set of standard values.

What to do if you eat rubber from the inside in front: possible causes

Often there is a non-standard situation in the form of the presence of different wear on tires installed on the same axle. Let's say the right wheel "ate" from the outer end, the left - from the inner. The exact reason is an incorrectly performed operation to adjust the geometry of the relative position of the suspension elements.

True reason

The list of actions in the case when he eats rubber from the outside in front is partly relevant when revealing rapid wear of the inner shoulders. When identifying increased abrasion of the treadmill from the inner edge, the nature of the malfunction should be attributed to one of the following groups:

1. The side blocks are erased evenly - the camber angle is incorrectly adjusted.
2. Sawtooth wear "herringbone" - convergence does not correspond to the norm.

It is possible to combine the fixed types of geometry of the worn tread. Under such circumstances, the masters talk about the incorrect setting and collapse, and convergence.
For your information. Not all machines have the ability to adjust all three wheel angles. In the presence of defects and the absence of the necessary adjustments, the cause should be sought in non-original and worn suspension components (silent blocks, etc. bushings). You should not discount the factory defects of tires or incorrect adjustment of the levers of the chassis.

There are frequent cases when it “eats” rubber from the back on one side. Worn silent blocks rear suspension – probable cause malfunctions. However, tuned racks and various spacers can also cause deviations in the geometry of the tires used.

Topical issues

Why the similarity collapses

A bad road has a negative impact not only on the resource of chassis components. It also leaves a negative imprint on their mutual arrangement. Timely control of adjustments is necessary in the following cases:

• After a strong impact on the curb, pits, potholes and other irregularities in the roadway.
• At the end of the replacement of suspension elements.

Attention! Wear on the consumable components of the suspension structure also knocks down the installation angles.

The components are original and the alignment is correct: the tire still wears unevenly

It is likely that the wheel bearing has failed. In the presence of such a malfunction, it is difficult not to notice the play, shaking the wheel in different directions. If you can deal with this ailment, then it is difficult to change the incorrect body geometry. And due to the bent bearing part, there may well be rubber on the inside of the rear or front of the car.

Premature wear does not meet the above conditions

Above, cases of asymmetric "eating" of rubber products are analyzed. The following cases of tread wear should be classified as symmetrical:

• Both sides: low tire pressure.
• Center: increased pressure in the tires.

Often there are situations when on the front / rear axle one of the tires is worn out faster than the other. The only argument in favor of this state of affairs is different pressure in tires located on the same axle. As a result of this, the car drives to the side and it is observed increased friction in a wheel with less air volume.

Verdict

Possible malfunctions that cause uneven tread wear are:

• Eats rubber from the inside edge. If a “herringbone” is observed on the treadmill, the problem is in the wrong convergence; uniform wear is a matter of a false camber angle.
• Eats rubber from the outer end - positive camber is to blame.

Alignment settings are within tolerance - see the following:

• The presence of wear rubber suspension units.
• The correctness of the form of the flanges of the rack.
• Compliance with the design of support bearings and various spacers to the requirements of the manufacturer.

The asymmetric geometry of the working part of the tire can also be caused by a damaged body. Another likely cause is a noticeable play in the hub bearing.

Why does the car eat rubber from the outside and inside of the front wheels? Read and Eliminate

Many motorists are interested in why the car eats rubber from the outside and inside of the front wheels. This is a fairly common problem. Moreover, the difficulty lies in the inability of the masters to accurately determine the cause of the breakdown, and yet it is far from always lying on the surface. Therefore, it is desirable for the owner to know the main types of breakdowns that lead to increased wear of parts. Some of the faults can be fixed right in the garage. This will avoid unnecessary trips to the service, although no one canceled the diagnostics. Knowing the reasons, you can avoid mistakes from negligent or inept mechanics.

Why does the car eat rubber from the outside and inside of the front wheels? Everyone knows that car tires wears out over time, and, first of all, it concerns the front wheels. There are several factors at once that influence this process. Actually, not too active tire wear for a car is the norm. First of all, the tires on the inside of the wheel are erased. This is due to the presence of castor. In theory, under normal conditions, wear on the wheel becomes noticeable only after 2-3 seasons. With more rapid wear you need to look for the cause of the problem.

The hydrometeorological center warned of a decrease in the grain harvest / Surfingbird

The grain harvest in Russia this year will be 15-20% lower than last year, Dmitry Kiktev, head of the Russian Hydrometeorological Center, believes. Last year, Russia harvested a record 135.4 million tons of grain

The hydrometeorological center expects that the grain harvest in Russia this year will be 15-20% lower than last year. This is with reference to the words of the acting director of the Hydrometeorological Center of Russia Dmitry Kiktev, Interfax reports.

“Forecast of the Hydrometeorological Center - this year's harvest for cereals and legumes is expected to be approximately 15-20% lower than last year,” Kiktev said.

Kiktev also recalled that in the first half of June, atmospheric and soil droughts were noted in the North Caucasus, in the Volga and Southern federal districts. According to him, heavy rainfall, which took place in the last two weeks in some areas, "was unevenly distributed, very variegated."

However, now the weather conditions for the ripening of grain in Russia are assessed by meteorologists as "normal" and "satisfactory". “That is, the situation is not alarming,” he added, recalling that in 2017 Russia harvested a record harvest in its history.

According to Rosstat, 135.4 million tons of grain were harvested in 2017, more than in the entire history of Russia.

Earlier, the head of the Ministry of Agriculture, Dmitry Patrushev, said that this year Russia expects a harvest of 100 million tons of grain due to drought in the southern regions of Russia. At the same time, according to him, grain exports from Russia this year will amount to 40-45 million tons.

“About 100 million tons - we hope that we will collect such a volume of grain this year. At the same time, it must be clearly understood that the forecast for the future may be changed depending on how the weather conditions develop, ”Patrushev said in early July (quoted by TASS).

The Minister noted that the situation with the forecast for grain changes regularly. “There will be an opportunity to collect more, of course, we will make every effort and we will do it,” Patrushev added.

Tires can be called the link between the car and the road surface. That is why for many decades the composition and design of tires has been constantly improved. According to the accepted rules, the car is allowed to participate in road traffic only if the wheels are in good condition. Inspection of tires from all sides allows you to get information about their condition, the technical condition of the car and the peculiarities of the owner's driving style.

Why does he eat rubber is a fairly common question that can be found on various automotive forums. Indeed, some time after the discovery of uneven wear, the wheels may be unusable, since severe wear significantly impairs handling, increases the braking distance, and reduces the stability of the vehicle on the road.

We carry out an inspection

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

The features of the car determine which side the wear is more severe: at the rear or at the front. In order to evaluate not only the suitability of tires, but also to determine the absence of problems with the technical condition of the car, all 4 wheels should be inspected.
In doing so, we note:

1. For a car that has a rear drive axle, it is the rear wheels that will be worn out more, for a front-wheel drive car, on the contrary, the front ones. This is due to the fact that the transmission of torque leads to an increase in the frictional force between the wheel and the road.
2. If, for example, Fiat Albea has disc brakes at the front and drum brakes at the rear - the front wheels will be worn out to a greater extent. This is due to the fact that the efficiency of disc brakes is higher. Often, severe abrasion of one or another part of the wheel occurs during braking, since at this moment there is a large load on the axle.

Driving style always determines the degree, the rate of wear. The more during the movement of acceleration and deceleration, the greater the wear.

When inspecting, it should be borne in mind that the cases under consideration determine uniform wear over the entire surface. What eats rubber unevenly? The answer is quite simple - there is a malfunction that leads to this.

It is possible to determine that the wheels are more eaten from the inside or outside only after a fairly long period of time. This is due to the fact that only after a few hundred kilometers this will become visible without the use of special instruments for measuring the tread size.

Wear of steered and driven wheels

An important point can be called something that eats rubber from the inside and outside of the driving and steered wheels in different ways, even in the absence of a malfunction. This is due to the following points:

1. At the time of the turn, the steered wheels grip the road surface with the inner or outer side of the tire, which is associated with the features of the steering system. Therefore, Fiat Albea may have tires with uneven wear. However, a similar phenomenon manifests itself after several thousand kilometers.
2. The wheels to which the torque is transmitted wear out to a greater extent in the middle - it eats rubber in the place where the load and friction force are concentrated.

If the steered wheels are driving, then the two phenomena are summed up and uniform wear occurs. A similar phenomenon is typical for a front-wheel drive vehicle. What eats uneven tires in this case - the answer lies in the presence of a malfunction.

Frequent problems

When considering why Fiat Albea has tires with varying degrees of wear, it should be noted that in some cases the problem manifests itself after several hundred kilometers of travel. We single out the following reasons for what eats rubber unevenly:

What eats rubber - quite a lot of answers. A Fiat or other car should be checked according to a certain pattern to identify the problem. This is due to the fact that even a simple cause, which will take little time and effort to eliminate, can lead to significant problems.

Pressure unevenness

The reason, which is the answer to the question of what eats rubber, can be called uneven pressure on wheels mounted on the same axle. In such a case, it is also possible for the vehicle to pull to one side. An example is when a Fiat has one front tire with 1.5 atmospheres and the other with 2.0 atmospheres.

In order to check this, it is enough to visit a gas station or station Maintenance. After checking the pressure, you need to equalize it, after a while you can check whether the pressure difference is the cause of uneven wear.

The collapse of convergence

On the inside or outside, eating may occur due to the incorrect location of the wheels relative to the vehicle body. In this case, after a long time, severe abrasion can occur on either side. Considering this problem, the following nuances should be noted:

1. Camber is an indicator that is responsible for the tilt along the vertical axis.
2. Convergence is an indicator that is responsible for the position of the wheel when turning.

Similar indicators apply only to the front axle. What can strongly eat up the wheels after a few kilometers of the distance traveled?

If you knock down the camber settings, the cord wears out. At the same time, it eats the cord in different ways, depending on how the reset of the set parameters occurred. After a few hundred kilometers, the problem can manifest itself clearly, up to complete abrasion of the tread to the base of the cord.

Considering such a question, we note the following:

1. If it eats up the inside, then this indicates an excessive inclination inward. This situation is called negative collapse. This situation occurs quite often.
2. If the outer edge wears quickly, then this is positive wear. In this case, the wheels are tilted in different directions.

After 300-500 kilometers of the distance traveled, even new tire may fall into complete disrepair. However, it should be borne in mind that zero camber leads to uniform, but increased wear. This situation also leads to a significant increase in fuel consumption, as well as an increase in rolling resistance.

Knocking down the settings takes place for the following reasons:

Checking the collapse of the convergence at the service station takes a little time. Modern equipment allows you to quickly and accurately check the collapse of the toe. Experienced craftsmen perform the work of setting the desired parameters in a short time.

Not only different, but also low pressure can lead to a decrease in the life of the purchased tire. This is due to the fact that tire manufacturers create a design taking into account the recommended operating conditions. If you operate the wheels with low pressure, it begins to wear out quickly. In this case, the load will fall on the part that is not intended for this.

A small pressure indicator determines the following:

1. The structure begins to sag at the edges.
2. The rim may come into contact with the surface of the tire, which will increase wear.

However, high pressure also causes eating to begin in the central part.

That is why you should constantly pay attention to what pressure. It is worth inflating the wheels to the rate recommended by the manufacturer.

Manufacturing defects

There is a low probability that a marriage was made during the manufacture and uneven wear occurs due to the irregular shape of the product. That is why you should purchase products only from trusted manufacturers.

Among the most common problems are the wrong composition of the rubber used, the wrong shape of the court, and other defects. Unfortunately, it is practically impossible to check the quality of tires without special equipment.

Tire aging

Even though rubber tends to wear out before its expiration date, there is a time limit. Aging rubber can cause it to wear unevenly and severely. It is also worth noting that improper storage can lead to rapid aging of rubber.

All manufacturers indicate how long a product can last under certain operating conditions. It also specifies how it should be stored.

The aging of rubber leads to the fact that it loses its tightness and the structure becomes porous. After a while, moisture begins to penetrate deep into the structure. Typically, manufacturers use metal cord to reinforce the structure. Moisture leads to the destruction of the metal base. According to accepted standards, a tire cannot be used after 10 years from the date of its release.

Other reasons

The above reasons can lead to severe surface abrasion after a few hundred kilometers. However, some malfunctions can also lead to minor wear, which will appear after several thousand traveled distances. Such reasons include:

1. Suspension failure. If camber is associated with the front suspension, then eating out the rear rubber may be due to a suspension malfunction. Incorrect arrangement of some elements can cause the wheels to be located at a certain angle. An example is the violation of the position of the racks, as well as levers and other elements that affect the position of the rim.
2. Changes in body geometry after an impact can also cause uneven wear. It is possible to identify such a situation only if certain equipment is available.
3. The nature of the disc you are using can also cause the problem in question. For example, after a strong blow, the shape of the disk may be broken.

Types of tire wear

The above causes can also lead to tire wear on the inside. However, they are quite rare. Body geometry changes after a hard impact, suspension failure causing wheel tilt is often repaired sooner, and modern rims are highly durable.

Epilogue

In conclusion, we note that the timely detection of the problem will eliminate the problem and preserve the integrity of the tire. Timely detection of the problem is possible with a constant visit to the service station. When pumping up wheels or conducting suspension diagnostics, you should pay attention to the condition of the tread.

Tires are one of the most wear and tear parts of a car. But what if they wear unevenly. To begin with, this uneven tire wear should be correctly identified in order to determine its causes. How does tire wear unevenly?

• in various places of the circumference - at certain points of the tread it is heavily worn (spots),
• on the different side of the tire - the outer, inner side of the tire or its central area around the entire circumference,
• one tire wears out much faster than the others,
• a pair of front or rear tires wear out faster.

Let's now give the reasons and consider the nature of tire wear for each cause. We will consider these reasons from the most common to the least common.

The tire is worn in the center or on the sides. The reason is insufficient or excessive tire pressure.

Incorrectly exposed will certainly lead to the fact that their abrasion proceeds unevenly. Trying to identify this cause on specific worn wheels is a waste of time. The pressure can change in each wheel differently, even if you always pump up only all four wheels.

But this reason can be determined by the nature of the wear of the tread itself. The fact is that an under-inflated tire, as you know, sags, and therefore the sides of the working surface wear out faster. But for over-inflated tires, on the contrary, the central part is erased faster, since under excess pressure it is this pressure that pushes out the most, as a result of which, the most load falls on the axis of the circle.

The result of driving on overinflated (top) and underinflated (bottom) tires

Only certain areas of the tire are worn out. The reason is a deformed disc or wheel balance is disturbed

A deformed (crumpled, "figure eight", etc.) disc can also often cause uneven wear of rubber. In this case, wear will occur in certain places (spots) of the tread. If the disk "eights", then the wear will be in the form of two spots: one on one side of the tire in a certain place, and the second - in the diametrically opposite place of the tire and on the opposite side. When the disk is deformed, the tire wears out very quickly, depending on the degree of deformation, of course.

The tire is subject to similar wear in the case of wheel imbalance. Although, this happens much more slowly than with a deformed disk.

And in both cases, an additional symptom is a beating on the steering wheel or throughout the car. A visual inspection of a worn wheel will help identify this deformation.

Sometimes the rubber itself can become the cause of increased wear - its marriage in the form of a broken metal cord. The cord can burst if the rubber has already worn out significantly.

Only the inner or outer side of the front wheels wears out. Cause - wheel alignment

If the front wheel alignment is out of alignment, then your two front wheels are not parallel to each other. They either "clubfoot" - they look forward, a little to the center with the projection of the direction, or they are inclined to one side or another relative to the vertical axis.

As a result of this, you get excessive wear on the rubber of only the front wheels, either on the inside or on the outside.

If a similar situation occurred with the rear wheels, then there is a bent beam (if any) or one of the failed (possibly also bent) suspension elements.

The outer side of the tires can also wear out due to a faulty silent block or ball joints.

Only one wheel wears out. Cause - something happened in the suspension or wedge brakes

If a component in your suspension is worn or loose, such as a leaky strut, it can lead to excessive tire wear on that particular wheel. If any part of the suspension is not working properly, the wheel will bounce more or it will be harder to go over bumps in the road. This creates additional friction on that tire, causing a significant reduction in tire life and tread condition.

Here, as a rule, uniform tire wear occurs only on one wheel.

Now imagine that you are driving around all day with a little pressure on the brake with your foot. This is what it's like, if somebody wedges brake component, such as a caliper (its piston). This usually happens only on one wheel, and because of this, it wears out faster (even wear occurs).

Only the front wheels wear out. Reason - something happened in the steering

Almost every part of the steering system can also lead to tire wear. But here we will only talk about the front wheels, and the nature of wear can be completely different: both in spots and on one side of the tire around the entire circumference of the tread.
