The reason for eating the fetus
Inaccurate positioning of four wheels leads to four tires not in the horizontal and vertical straight lines required by the standard, so two wheels on the same side will eat tires when driving, or the front wheel or rear wheel mainly does not go in a straight line, and the vehicle corrects itself, resulting in abnormal friction between a certain part of a tire and the ground and accelerating wear.
Inaccurate toe-in adjustment can also lead to tire wear. What is toe-in, that is, the angle at which the front wheel leans slightly inward is similar to the inner figure of eight. This is the best angle for high-speed and stable driving. All cars have their own toe angle. If this angle is not adjusted properly, they will eat tires. Same as the first reason.
Failure of steering gear will also cause tire gnawing deviation. The uneven deformation of the girder will also cause the tire to bite. For example, some accident cars eat tires because the beam is deformed.
