What is the reason why cars eat tires?
1. Tires with regular width and basically the same width have serious wear on the upper and lower edges, which must be caused by insufficient tire pressure. If the arch plate is excluded.
Solution: Check and replenish the tire pressure.
2. The tire wears evenly, but the amount of wear is large, and there is no eccentric wear and wave wear. The general reason is that the road conditions are poor and the tire patterns are not suitable for special roads; Improper user maintenance, mixed tires, and no timely transposition, timely transposition of tires can increase the mileage by 20%; Severe overload, resulting in tire overload; The higher the ambient temperature, the shorter the tire life.
Solution: Replace qualified tires.
3. One rim of the whole vehicle tire is regularly worn, which is a typical damage to the rubber sleeve of the thrust rod.
Solution: change the rubber sleeve and adjust the wheelbase. Rubber sleeves must be replaced periodically or according to mileage.
4. If two or four tires appear on a bridge at the same time, the tires on both sides will eat regularly and evenly.
Solution: Check whether the riding bolt of the spring bow plate is loose and whether the central bolt of the bow plate is broken. If there is any problem, carry out corresponding maintenance.
5. One or more tires are seriously worn at the top groove depression, which is caused by the serious wear of the balance beam or the looseness of the tie rod.
Solution: Repair or replace the balance beam pin and balance beam, tighten the pull rod, and remember that the balance beam must be oiled frequently.
6. One or two large pieces of tire tread are worn, and two tires appear at the same time, which is basically the reason for braking the hub.
Solution: Boring the drum or replacing it.
7. One or both sides of a single tire have serious irregular eating, which is basically caused by the deformation of the steel ring.
Solution: Replace the steel ring. You can buy high-quality rims by eating less steamed bread. Don't force it!
8. Too much difference between the old and new diagonal tires will also cause unexplained eating.
Solution: Replace the tires with new ones.
The above introduces the relevant content of why cars eat tires. Let's take a look at how to prevent cars from "eating tires".
How to avoid car "eating tires"
1, 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.
Step 2 Adjust the 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.
3. 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.
4, regular wheel dynamic balance.
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".
5. Pay attention to tire maintenance and transposition.
I'm sure many people have heard that a car needs to change its tires at regular intervals, 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.
