1. The main cause of early wear in the middle of the tire is excessive air volume. Appropriately increasing the inflation volume of the tire can reduce the rolling resistance of the tire and save fuel. However, when the aeration rate is too large, not only does it affect the damping performance of the tire, but it also causes the tire deformation to be excessive, and the contact area with the ground is reduced. Normal wear can only be borne by the middle of the tread, resulting in early wear.
2. The main cause of excessive wear on both sides of the tire is the lack of inflation or long-term overloaded driving. When the aeration is small or the load is heavy, the contact surface between the tire and the ground is large, so that the two sides of the tire come into contact with the ground to participate in work and form early wear.
3. The main cause of excessive wear on one side of the tire is the inaccurate positioning of the tire. When the camber angle is too large, early wear on the outside of the tire occurs, and when the camber angle is too small or absent, the inner edge of the tire forms early wear.
Tire wear is mainly caused by the friction generated by the sliding between the tire and the ground. If the tire is improperly used or positioned incorrectly, it will cause abnormal wear and tear. Common abnormal wear is as follows:
