The Function Of Automobile Tire

Increasing the speed of the vehicle, especially in the fast driving, the service life of the tire is significantly reduced. Because the vehicle is moving fast, the tire in a unit time with the ground contact number is more frequent, friction is more frequent, so that the tire deformation frequency. 

At the same time, the circumferential and lateral distortion of the carcass also increases. When the speed reaches the critical speed, the vibration of the tire crown surface appears wave deformation and forms the stationary wave. This stationary wave can cause a tire to burst a few minutes after it is generated. This is due to the lag loss caused by the failure of the tire to recover from its deformation, most of the kinetic energy is absorbed and converted into heat, thus raising the tire temperature, accelerating the aging of the rubber and reducing the fatigue strength of the cord layer.
