What's wrong with eating the fetus before the golden cup sea lion?

Inaccurate positioning of four wheels leads to four tires not on 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 straight, 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.

B. Inaccurate toe-in adjustment can also lead to tire wear. What is toe-in? It means that the front wheel leans slightly inward at an angle, 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. The reason is the same as the first one.

C. Failure of the steering gear will also cause deviation of tire eating.

D uneven deformation of the girder may also lead to tire wear. For example, some accident cars eat tires because the beam is deformed.

E. If the air pressure difference between each tire is too large, the tire will be eaten. Tires of different specifications will also eat tires when mixed. The reason is the same, that is, the four feet are uncoordinated, and when you work in an unsmooth environment, you will eat tires because you can't eat anything else. Ha ha ha ha.
