What happened to BYD Song's rear wheel eating tires?
Eating tires refers to abnormal wear on the inside or outside of one or more tires. That is to say, compared with other tires, a certain part of the tire wears away quickly. The main reason of tire gnawing is that the data of four-wheel alignment is wrong, so it is necessary to adjust the data of four-wheel alignment. Otherwise, it will affect the service life of tires and is not conducive to safe driving.
The causes of tire wear are as follows:
1, four-wheel alignment is not accurate, resulting in two wheels on the same side eating tires when driving, or when the front and rear wheels are not aligned. Vehicle self-correction leads to abnormal increase of friction in a certain part of tire, which accelerates wear;
2. Inappropriate toe-in adjustment can also lead to fetal eating. That is to say, the front wheel is slightly tilted inward, and the angle is similar to that in the inner picture. This is the best angle for high-speed and stable driving. All cars have their own toe angle. If the angle is not adjusted well, it will also eat tires;
3. Failure of steering gear may also lead to tire biting, deviation, etc.
4. Uneven and deformed girders can also lead to tire wear. For example, some accident vehicles eat tires because the beam is deformed;
5. Tires of different specifications are mixed together, and the air pressure of each tire is very different, which will lead to eating tires.
Ways to avoid eating the fetus:
1. Adjust the tire pressure and always keep the normal tire pressure. The normal tire pressure value can refer to the manufacturer's recommended value, which can be found in the user manual and the small door of the fuel tank cover.
2. Check the wheel dynamic balance of the tire regularly. If imbalance is found, balance lead blocks shall be installed;
3. Pay attention to tire maintenance and transposition. It is best to change the tires when the vehicle travels 8000- 10000 km to make the tires wear evenly and prolong the service life;
4. Check whether the hub screw is loose;
5, avoid overloading, and pay attention to the tire stress balance.
