|Air pressure is the life gate of a tire. Too high and too low will shorten its service life. If the air pressure is too low, the carcass deformation will increase, the sidewall will be prone to cracks, and at the same time, the flexing motion will occur, resulting in excessive heat generation, which will cause the rubber to age, the ply fatigue, and the cord to break. If the air pressure is too low, it will increase the ground contact area of the tire to accelerate the shoulder wear. If the air pressure is too high, the tire cord will be excessively stretched and deformed, and the elasticity of the carcass will decrease, which will increase the load on the car during driving. If the impact will cause internal cracking and blasting, the air pressure will also accelerate the crown. Wear and reduce rolling resistance.|
The front wheel positioning has a great influence on the service life of the tire, and the front wheel toe and the front wheel camber are the main factors. The front wheel camber mainly accelerates the wear of the shoulders, that is, the eccentric wear; the front wheel toe is too small and too large to accelerate the wear of the inner and outer sides of the tire.
In addition to handling the situation, the driver should choose the road surface to avoid sharp stones, glass, metal and other objects that may puncture and scratch the tire, avoiding the adhesion and corrosion of the chemical spilled material to the tire. When driving on a road with a large degree of arching, it is necessary to travel as much as possible in the middle, reducing the load on one side of the tire and increasing the uneven wear of the tire. Under normal circumstances, overloading 20% will reduce tire life by 30%, overloading 40% will reduce tire life by 50%; in addition, rapid turn, emergency braking, high-speed start and rapid acceleration will have an impact on tire damage, is the driver To be avoided in driving.The position of the tire in the various parts of the car is very important, which has a great influence on the driving performance of the car. The service life of the tire directly affects the transportation economy.
