Tires wear abnormally, what is the cause and what is the solution?

Jan 05,2019


Tire wear is mainly caused by the friction generated by sliding between the tire and the ground. Automobile starting, turning and braking and other driving conditions change constantly, turning speed is too fast, starting too fast, braking too fierce, tire wear is fast. In addition, tire wear is also related to the car's driving speed, the faster the driving speed, the more serious tire wear, the quality of the road surface also directly affects the friction between the tires and the ground, the road surface is poor, the tires and the ground sliding intensified, tire wear accelerated. The tire wear generated by the above situation is basically uniform, is normal wear. If the tire is not used properly or the front wheel alignment is not allowed, will produce faulty abnormal wear, common abnormal wear are as follows:

1、 Early wear of the central part of the tire

The main reason is over-inflation. Appropriate increase in tire inflation can reduce the rolling resistance of the tire and save fuel. However, when the inflation is too large, it not only affects the vibration damping performance of the tire, but also makes the tire deformation too large, the contact area with the ground is reduced, and the normal wear and tear can only be borne by the central part of the tread, forming early wear. If a wide tire is used on a narrow rim, it will also cause early wear of the central part.

2、 Tire wear on both sides is too large

The main reason is insufficient inflation, or long-term overloaded driving. When the inflation is small or the load is heavy, the contact surface between the tire and the ground is large, so that both sides of the tire and the ground contact to participate in the work and form early wear.

3、 One side of the tire wears too much

The main reason is that the front wheel alignment is out of alignment. When the camber angle of the front wheel is too large, the outer side of the tire will form early wear, and when the camber angle is too small or none, the inner side of the tire will form early wear.

4、 Tire tread jagged wear

The main reason is that the front wheel alignment adjustment is not proper or the position of the front suspension system is out of order, loose ball head, etc., so that the normal rolling wheel sliding or driving in the wheel alignment constantly change and form tire jagged wear.

5、 Individual tire wear

Individual wheels of the suspension system is not normal, support parts bending or individual wheel imbalance will cause early wear of individual tires. After this situation, should check the wear severely punished wheel positioning, independent suspension springs and vibration dampers work, at the same time should shorten the wheel shift cycle.

6、 Tires appear bald-shaped wear

In individual parts of the tire bald severe wear is the cause of poor tire balance. When the unbalanced wheel rotates at high speed, the individual parts of the force is large, wear faster, while the steering hair stop, poor maneuverability. If you notice a slight jitter in a particular speed direction while driving, you should balance the wheels to prevent bald-shaped wear.

In order to avoid the occurrence of the above abnormal wear, should pay attention to the following matters:

1. Pay attention to tire pressure

Air pressure is the lifeblood of the tire, too high and too low will shorten its service life. Air pressure is too low, the carcass deformation increases, the sidewalls are prone to cracks, at the same time produce flexural movement, resulting in excessive heat, prompting rubber aging, cord layer fatigue, cord breakage. Air pressure is too low, will also make the tire grounding area increases to accelerate tire shoulder wear. Air pressure is too high, will make the tire cord by excessive stretching deformation, the elasticity of the carcass decreases, so that the car in the driving load increases, such as in case of impact will produce internal cracking and bursting, at the same time the air pressure is too high will accelerate the tire crown abrasion, and make the resistance to rolling performance decreases.

2, regularly check the front wheel alignment

Front wheel alignment on the service life of the tire has a greater impact, especially in front of the front wheel beam and front wheel camber as the main factor. Front wheel camber will mainly accelerate the wear of the tire shoulder, that is, bias wear; front wheel front beam is too small or too large is mainly to accelerate the wear of the tire inside and outside.

3, pay attention to driving style

Driving in addition to dealing with the situation, to choose the road surface driving, avoid sharp stones, glass, metal and other objects that may puncture and scratches tires, to avoid the chemical spills material on the tire adhesion, corrosion. Driving in the arch of the road, to try to drive in the center, to reduce the tire load on one side and make the tire wear uneven. In general, overloading 20% of the tire life is reduced by 30%, overloading 40% of the tire life is reduced by 50%; in addition to sharp turns, emergency braking, high-speed start and rapid acceleration will have an impact on the damage to the tires, is to be avoided in the car.
