What's wrong with the outer ring of the new Santana rear wheel?

1, four-wheel positioning is not accurate, so the four tires are 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 walk 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. I'm a little unclear about what I said, but I don't know how to express it. Anyway, imagine that the four wheels of a car should be on four fixed points of a rectangle. If they don't run like that, they will compete and cause tire wear.

2. Inappropriate toe-in adjustment can also lead to fetal eating. 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, they will eat tires. Same as the first reason.

3. Failure of steering gear will also cause tire gnawing deviation.

4. Uneven deformation of the girder will also cause tire gnawing. For example, some accident cars eat tires because the beam is deformed.

5. If the air pressure of each tire is too different, it will eat tires of different specifications. The reason is the same, that is, if you don't work in a smooth environment, you will eat tires because you can't eat anything else. Most tires can be corrected by adjusting toe-in and four-wheel alignment.
