Causes of abnormal tire wear
Nov 20,2024
Tire wear is mainly caused by the friction force generated by the sliding between the tire and the ground. The driving conditions of the car such as starting, turning and braking are constantly changing. If the turning speed is too fast, the starting is too fast, and the braking is too strong, the tires will wear quickly. In addition, tire wear is also related to the driving speed of the car. The faster the driving speed, the more serious the tire wear. The quality of the road also directly affects the friction between the tire and the ground. When the road is poor, the tire and the ground slip more. The wear accelerates. The tire wear caused by the above conditions is basically uniform and belongs to normal wear. If the tire is used improperly or the front wheel is not positioned correctly, it will produce faulty abnormal wear. The common abnormal wear is as follows:
(1) Early wear of the central part of the tire: The main reason is that the inflation is too large. Properly increasing the inflation of the tire can reduce the rolling resistance of the tire and save fuel. However, when the amount of inflation is too large, it will not only affect the damping performance of the tire, but also cause the tire to deform too much and reduce the contact area with the ground. Normal wear can only be borne by the central part of the tread, resulting in early wear. If you choose a wide tire on a narrow rim, it will also cause early wear in the central part.
(2) Excessive wear on both sides of the tire: The main reason is insufficient inflation or long-term overload driving. When the amount of 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 contact the ground to participate in work and form early wear.
(3) excessive wear on one side of the tire: the main reason is the misalignment of the front wheel. When the camber angle of the front wheel is too large, the outer edge of the tire will form early wear, and when the camber angle is too small or not, the inner edge of the tire will form early wear.
(4) Jagged wear on the tire tread: The main reason is improper adjustment of the front wheel positioning or abnormal position of the front suspension system, loose ball head, etc., which causes the normal rolling wheels to slip or the wheel positioning constantly changes during driving to form tires. Serrated wear.
(5) Large amount of individual tire wear: abnormal suspension system of individual wheels, bending of supports or imbalance of individual wheels will cause early wear of individual tires. After this situation occurs, check the positioning of the severely worn wheels, the working conditions of the independent suspension springs and shock absorbers, and shorten the wheel rotation cycle.
