1, the center of gravity of the vehicle is unstable, some models have rear engines, or because of other factors such as bulletproof body, the center of gravity shifts and the rear wheels of the tires are seriously worn;
2. The four-wheel alignment of the tire is not good, and the tire is eccentric, resulting in abnormal wear;
3. The vehicle corrects itself, resulting in abnormal friction between a certain part of the tire and the ground, increasing accelerated wear;
4. The toe-in adjustment is not accurate. The angle at which the front wheel leans slightly inward is similar to the inner figure of eight, which is the angle of high-speed and stable driving. All cars have their own toe angle. If this angle is not adjusted properly, they will have a miscarriage.
