The use of tire at high pressure, the contact area of the tire and the road becomes small, and the pressure increases, the central tread wear speed; the tire pressure is too high, the matrix stress increases, the cord layer is decreased, tensile strength of excessive elasticity, easy to be sharp objects, greatly impact matrix may also be blasting. Besides, Baotou North Mercedes parts high tire pressure will also reduce the grip ability of the tire, extend the brake distance, affect the comfort and increase the wear of the chassis components.

Low pressure of 2. fetus

The low tire pressure is more serious to the tire. This is mainly due to the side of the tire deformation increases, the cord tire body layer resulting from the alternating stress, the fatigue damage will accelerate the cord compression cycle, is the beginning of the glue line out, then quickly broken, so that the tire is scrapped prematurely; the tire with low pressure rolling, will exacerbate the tire heat temperature, when the temperature is too high will result in tire carcass delamination, friction cord, delamination in place at a higher temperature, are also more likely to cause fetal side blasting; fetal depression, tread the central load smaller, edge load increases, the serious wear shoulder pattern. The tire pressure will not only aggravate the wear of the tire, but also increase the rolling resistance, and increase the fuel consumption.

3. tire overloading

When overloading, the characteristics of the tire damage are similar to the damage at low pressure, but the overloading is more serious for the wear and damage of the tire. Because the tire deformation is large, the stress on the side side is too large, which makes the tire material fatigue and its strength decrease faster. The tire cord is most easily broken or explode on the side of the tire. When the overloaded tire is rolling onto the stone, it often occurs the crown blasting. It has been proved by practice that the overloading 20% will reduce the tire life by 30% and the rolling limit will increase by 40%. Overloading inevitably causes early damage or scrap of the tire.

Failure of the 4. chassis

In running, due to the poor technical condition of some chassis parts, it is also an important reason for the abnormal wear or damage of the North Mercedes spare tire in Baotou. One of the biggest damage to the tire is the front wheel positioning is not accurate, especially before the beam is too large or too small will appear so that the front wheel is rolling with sliding phenomenon, caused by the side of the tread pattern wear, the other side pattern lint, even deviate from the standard is not much, can also cause partial wear tread. There is an error in the front wheel positioning, which not only causes damage to the tire, but also directly affects the steering performance. In addition, the frame or suspension bridge after deformation, displacement, steering rod ball or steering knuckle Songkuang, Baotou Benz accessories wheel bearing clearance is too large, the brake drag or locking, abnormal wear will cause the tire. Therefore, regular vehicle maintenance and front wheel alignment, especially steering and braking system, will maintain good technical conditions, and will play a very important role in reducing tire wear and prolonging service life.

In addition to the above condition reason, there is a direct relationship between another reason to shorten the service life of tyre with drivers such as: rapid starting, acceleration, braking, sharp sharp sharp turning, speeding, move in direction and do not pay attention to the choice of the road, rolling obstacle, inspection and repair is not timely.
