What are the causes of car tire wear?

Causes of total tire breakage:

1.The tire pressure is too high.

When the tire is used under high air pressure, the contact area between the tire and the road surface becomes smaller, and the pressure increases, which accelerates the wear of the middle of the tread; When the tire pressure is too high, the stress of the carcass increases, so that the cord layer is subjected to excessive tensile strength decreases, the elasticity is reduced, it is easy to be punctured by sharp objects, and the carcass may also burst when it is subjected to a large impact. In addition, high tire pressure will also reduce the grip of the tire, resulting in longer braking distance; Affects comfort and exacerbates wear and tear on chassis components.

2.Tire pressure is too low.

Tire pressure that is too low can cause more serious damage to the tire. This is mainly due to the increase of sidewall deformation, so that the cord layer in the carcass produces excessive alternating stress, periodic compression deformation will accelerate the fatigue damage of the cord, at first the rubber line is detached, and then it will be quickly broken, so that the tire is scrapped prematurely; When the tire rolls at low air pressure, it will aggravate the heat generation temperature of the tire, and when the tire temperature is too high, it will also lead to local delamination of the carcass A, friction between the cords, and the temperature at the place of delamination.

Higher, it is also more likely to cause sidewall bursting; When the tire pressure is low, the middle load of the tread becomes smaller, and the edge load increases, causing the shoulder pattern to be severely worn. Low tire pressure not only increases tire wear, but also increases rolling resistance and increases fuel consumption.

3.Overloaded tires.

The characteristics of tire damage during overloading are similar to those when driving at low air pressure, but the wear and damage to tires from overloading is more severe. Due to the large deformation of the tire, the stress on the sidewall is too large, so that the fatigue of the tire material and its strength are reduced faster, and the cord layer is most likely to break or burst on the sidewall; When an overloaded tire rolls into a stone, a crown burst often occurs. Practice has shown that with a 20% overload, tire life will be reduced by 30% and rolling resistance will be increased by 40%.

Overloading inevitably causes early damage or scrap of tires.

4.Failure of the chassis.

In driving, due to the poor technical condition of some mechanisms of the automobile chassis, it is also an important cause of abnormal wear or damage to tires. Among them, the biggest damage to the tire is the inaccurate alignment of the front wheel, especially the front wheel is too large or too small will make the front wheel appear rolling with slippery phenomenon, resulting in serious wear of the tread on one side, and the pattern on the other side, even if the deviation from the standard is not much, it will also lead to the eccentric wear of the tread. Faulty front wheel alignment not only causes damage to the tires, but also directly affects steering performance.

In addition, the deformation of the frame or suspension, the displacement of the rear axle, the loose ball joint or knuckle of the steering tie rod, the excessive clearance of the wheel bearings, and the lag or locking of the brakes will cause abnormal wear and tear of the tires. Therefore, regular maintenance of the vehicle and front wheel alignment, especially the steering and braking systems, to keep it in good technical condition, will play a very important role in reducing tire wear and prolonging the service life.

In addition to the above-mentioned reasons for vehicle conditions, another reason for shortening the service life of tires is directly related to the driver, such as: sharp start, sharp acceleration, sharp braking, sharp turning, speeding, playing in the same direction, not paying attention to the choice of road surface, rolling obstacles, inspection and repair are not timely, etc.

1. Tire pressure is abnormal for a long time Tire pressure is the life of the tire, the air pressure is too low, the carcass deformation increases, the sidewall is prone to cracks, and at the same time leads to excessive heat generation, which promotes the aging of rubber, fatigue of the cord layer, and breaking of the cord. If the air pressure is too low, it will also increase the ground contact area of the tire and accelerate the wear of the shoulder; If the air pressure is too high, the tire cord will be subjected to excessive stretch deformation, the elasticity of the carcass will decrease, and the load on the car will increase during driving, and the impact will produce internal cracks and bursts, and at the same time, the high air pressure will also accelerate the wear of the tire crown, and reduce the rolling resistance.

2. Inaccurate front wheel alignment The front wheel alignment has a great impact on the service life of the tire, especially the front wheel toe and front wheel camber are the main factors. The camber of the front wheel mainly accelerates the wear of the shoulder, that is, eccentric wear; The toe-in of the front wheels mainly accelerates the wear of the inside and outside of the tire.

3. Bad driving habits In addition to dealing with the situation in the driving, the driver should choose to drive on the road to avoid sharp stones, glass, metal, etc. that may puncture and scratch the tire, avoid the adhesion of chemical residues to the tire, and avoid the corrosion of the tire; When driving on the road surface with a large camber, it is necessary to drive in the center as much as possible to avoid and reduce the shift of the center of gravity of the car, and reduce the uneven tire wear due to the increase of tire load on one side; Reasonable loading is the basic common sense, in general, overload 20 tire life reduction 30, overload 40 tire life reduction 50; In addition, sharp turns, emergency braking, high-speed starts, and rapid acceleration will all have an impact on tire damage, which is something that drivers should avoid while driving.

First, the middle of the tread is seriously worn.

The main cause of excessive wear in the middle of the tread is that the tire pressure is higher than the standard pressure and the contact area with the ground is reduced. Excessive tire pressure not only easily causes the wear of the middle of the tire crown to increase, the bottom of the tread cracks, but also makes the cord layer overextended, and even breaks and breaks, and is easy to burst due to the impact of obstacles when driving at high speed on uneven roads.

Second, both sides of the tread are seriously worn.

The main reasons for excessive wear on both sides of the tread are insufficient tire pressure or overloading of the car. This will widen the crown grounding imprint, causing the crown to hit the ground on both shoulders and creating eccentric wear on both sides of the crown. Insufficient tire pressure or overloading of the car can also increase fuel consumption and cause the tire temperature to become too high and cause it to burst.

1.The ** part of the tire is worn early. The main reason: the tire inflation is too large, which not only affects the shock absorption performance of the tire, but also makes it.

2.Excessive wear on both sides of the tire. The main reason: insufficient tire inflation or long-term overload, so that the tire and the ground contact surface is large.

3.One side of the tire is worn too much. The main reason: it is caused by the wrong camber angle of the wheel. Solution: The axle can be repaired or replaced.

4.The tire tread appears jagged and worn. The main reasons: improper adjustment of the front wheel alignment or abnormal position of the front suspension system, loose ball joint, etc.

5.Excessive wear on individual tires. The main causes: It is due to the malfunction of the suspension system of individual wheels, the bending of the support frame, or the imbalance of individual wheels.

First of all, after searching for objects and walking on the road, it has a frictional force, and if this friction is long, it will slowly wear out, and it needs to be replaced after a long time.

One. The middle pattern of the tire is smoothed, which means that the tire pressure is too high. This can be the case with particularly wide tires.

If the tire has been hit with nitrogen, it is generally rarely ground in the middle, but if the air has been played, the water removal of the compressor is not good, and there is too much moisture in the air, and it is easy to have intermediate grinding.

Two. One side is smoothed, the other side is fine. Typical eccentric grinding.

In this case, there is a problem with the four-wheel alignment data, mainly because there is a problem with the toe-in, and it should be noted that it is not only the front wheel, but also the toe-in. Both the front and rear wheels have toe-in.

When the tires are eccentric, you can ventilate or redo the wheel alignment according to the situation.

If the tire pressure is too high, only the middle of the tread will touch the ground, and if it is too low, only the shoulders on both sides will touch the ground, which will cause the tire to wear out too quickly and lead to the premature end of the tire mileage life.

Abnormal wheel alignment can cause one side of the tire shoulder to wear faster than the rest of the tread, accelerating tire wear.

If the cause of abnormal wear and tear of your motor vehicle tires may be due to insufficient tire pressure or deviation of your road conditions or your personal driving habits, including the phenomenon of tire eating.

1.Driving style.

In addition to dealing with the situation when driving, it is also necessary to choose the road surface, avoid sharp stones, glass, metal and other objects that may puncture and scratch the tire, and avoid the adhesion and corrosion of chemicals spilled on the tire. When driving on roads with a large camber angle, try to drive on ** to reduce uneven tire wear caused by the increase in tire load on one side. Generally, overload 20% tire life will reduce tire life by 30%, overload 40% tire life will reduce tire life by 50%.

In addition, sharp turns, emergency braking, high-speed starts, and sharp acceleration will all have an impact on tire damage, and drivers should avoid it while driving.

Second, front wheel alignment.

Front wheel alignment has a significant impact on the service life of a tire, especially the toe-in and camber of the front wheels. The camber of the front wheels mainly accelerates the wear of the shoulders, that is, eccentric wear; The toe-in of the front wheels is too small and too large, mainly to accelerate the wear and tear inside and outside the tires. Third, tire pressure.

This is the fate of pneumatic tires. Too high or too low will shorten its lifespan. If the air pressure is too low, the deformation of the carcass increases, the sidewall is prone to cracks, and buckling movements occur at the same time, resulting in excessive heat generation, rubber aging, and tire collision ply and cord breakage.

If the air pressure is too low, it will increase the contact area of the tire and accelerate the wear of the shoulder. If the air pressure is too high, the tire cord will be subjected to excessive stretch deformation, and the elasticity of the tire carcass will be reduced, which will increase the load of the car during driving. If there is an impact, internal cracks and ** will occur.

At the same time, if the air pressure is too high, the crown of the tire will wear out and the rolling resistance will be reduced.

Causes of tire wear of automobiles: 1. Due to the transmission structure and load distribution, for four-wheel drive vehicles, due to terrain conditions or crankshaft drive, tires may be subject to uneven wear due to load distribution, on single-wheel drive vehicles (front or rear); 2. Tires mounted on drive shafts usually wear out faster. In addition, the unevenly distributed load between the front and rear axles also leads to different wear on tires on different axles; 3. Therefore, it is also recommended that after a period of use (about 10,000 km), the owner should change the wheel Xiaolu stove tire.
