1. Adjust tire pressure
You should know that tire pressure is too high or too low, which will cause uneven tire wear. When the tire pressure is too low, the tire will bend inward, which will easily lead to serious tire edge wear; When the tire pressure is too high, the middle tread of the tire will wear faster. Therefore, pay more attention to whether the tire pressure is in a normal state every day. Generally, it is enough to inflate and deflate according to the tire pressure stipulated by the car.
2. Do wheel dynamic balance regularly.
Due to the influence of manufacturing process or some external factors, the quality of each part of the wheel may be uneven. Therefore, when the automobile wheel rotates at high speed, it will form a dynamic unbalanced state. In order to avoid or eliminate this phenomenon, it is necessary to correct the balance of each edge part of the wheel by adding counterweight under dynamic conditions, so as to avoid the phenomenon of "eating tires".
3. Do four-wheel positioning regularly.
Four-wheel alignment has the functions of increasing driving safety, prolonging tire service life, reducing fuel consumption, reducing tire wear (avoiding eating tires) and reducing suspension parts wear, so it is necessary to go to 4S shops or professional repair shops regularly for four-wheel alignment. It is recommended to do it at least once a year, or once every 10 thousand kilometers.
4. Pay attention to tire maintenance and transposition.
I'm sure many people have heard that every time a car walks a certain distance, the tires have to be transposed, right? Generally, every 5,000 kilometers of a vehicle, it is necessary to change the tires. But how to change them? Generally, it is better to change the tire diagonally, because it can maintain the tire normally and make the tire wear more evenly, thus prolonging the tire life.
5. Check whether the hub screw is loose.
Loose hub bearing, leaf spring riding bolt not tightened as required, loose suspension, etc. It will cause the tires to sway from side to side during driving, resulting in abnormal tire wear. Therefore, when maintaining the vehicle, carefully check the screws around the wheel and hub to see if they are loose.
6. We often adjust toe-in. We can consider serious wear and tear. If our toe-in is adjusted very small, that is, the figure of eight, the vehicle will slide sideways when driving, and the wear position is also on both sides of the tire, so adjusting the toe-in is also a more effective and convenient method.
7. Say a simple case, the vehicle wear of a motorcade means that the tire on the outside of the front wheel is seriously worn and the inclination angle of the front wheel of the vehicle is reasonable. Finally, it is found that the container front end of the vehicle is relatively short and the connection position with the main vehicle is relatively backward; In this case, after the vehicle pulls the goods again, the center of gravity will drop to the rear position. It is suggested to move the traction seat forward by two bolt holes (about 10cm), so that the center of gravity will move forward and press on the main vehicle after pulling the goods, which can correct the camber of the front wheel and ensure the normal contact of the vehicle tires.
Extended data:
The reason of automobile tire gnawing;
Generally speaking, there are four reasons.
1. Four-wheel alignment is not accurate: if four tires are not in the horizontal and vertical straight lines required by the standard, two wheels on the same side will eat tires when driving, or the front wheel or rear wheel will not go in a straight line, and the vehicle will correct itself, resulting in an abnormal increase in friction between a certain part of a tire and the ground and accelerating wear. ?
2. Inappropriate toe-in adjustment can also cause fetal eating. What is toe-in? That is, 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 you don't adjust this angle properly, you will have a baby.
4. Uneven and deformed girders can also lead to tire wear. For example, some accident cars eat tires because the beam is deformed.
If the air pressure of each tire is too different, it will eat the tire. If tires of different specifications are mixed together, they will eat tires. The reason is the same, that is, the four feet are not harmonious. If you don't work in a smooth environment, you will eat the baby.
