What is the reason why the inner side of the rear tire is flat?

Incorrect positioning of four wheels: if four tires are not on two straight lines required by the standard, then two wheels on the same side will eat tires when driving; Or the front wheel or the rear wheel, mainly does not walk in a straight line, and the vehicle corrects itself, which leads to an abnormal increase in friction between a certain part of the tire and the ground and accelerates wear.

Incorrect toe-in adjustment: it can also cause fetal eating. Toe is the angle at which the front wheel leans slightly inward, 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 have a miscarriage.

Steering gear failure: it will also cause tire eating, deviation and so on.

Uneven and deformed beams can also cause tire eating: for example, some accident cars eat tires because the beams are deformed.

If the air pressure of each tire is too different, it will eat the tires, indicating that it is out of balance.

Tires of different specifications are mixed together and will eat tires.

Long-term tire pressure is too high or too low: Too high or too low tire pressure will cause uneven contact between the tire and the ground, leading to tire biting.
