Safety is important Nine conditions of tire wear

In everyday driving, the safety of car tires is very important. Is your tire safe? Is it regularly checked regularly?

The four wheels of the car must be checked regularly every month. Check the tire surface for cracks or scratches at the same time. It's best to put gloves on the inside of the tire and check for suspicious traces. As long as the slightest suspicious point is found, you should immediately ask the car dealer to make a detailed inspection. Tired tires do not want to throw. If it is found that the surface of the tire is not properly worn, it should be thought that there may be problems with the adjustment of the toe of the wheel and it is necessary to repair it.

Tire wear is roughly divided into the following situations:

1. Wear on the outside edge Cause: If the outside edge of the tire is worn out, it means that the tire is often under-inflated, that is, the pressure is not enough.

Solution: Check the tire pressure several times. If possible, inflate according to the "highway" standard, which means that there is an additional 30,000 Pa over normal standards.

2. Convex and corrugated wear causes: If it is found that the tire on both sides of the ground is convex wear, and the tire is also a corrugated wear, indicating that the car's shock absorbers, bearings and ball joints and other components wear more serious.

Solution: It is recommended that you check the wear of the suspension system and replace worn parts before replacing the tire. Otherwise, even if you change the tires will not help.

3. Uniform wear of the surface Cause: Uniform wear of the tire is a normal phenomenon. Once the pattern is dried, the tire must be replaced.

Solution: If the wear has reached the standard depth of the tire tread (usually 1.6mm width is greater than 175mm tires 2mm), it will be replaced.

4. "Dark injury" in the tire

Cause: After the vehicle collides with a hard object or after it has been aborted, the rubber layer of the tire will have serious scratches, affecting the degree of sealing.

Solution: In this case, the tire will leak and burst. If the wound is small, it can be repaired to meet the needs of the occasion. However, if you want to travel long distances, you must replace them immediately.

5. Wear in the center part Cause: If the central area of ​​the tire's land area is found to be heavily worn, this means that the tire is often over-inflated, which will accelerate tire wear.

Solution: Check if the pressure gauge is accurate and adjust the pressure. The tires need to be inflated only when they are driving at high speed or when they are carrying heavy loads. It is not necessary to use them under normal conditions.

6. Causes of tire side cracks: Poor maintenance or driving on multi-stone roads and construction sites, so that hard objects come in contact with the tires, causing damage to the inner layers of the tires under heavy pressure.

Solution: If the repair cost is not too expensive, replace the tire properly. The current tires are more squeamish than the original and should be properly maintained.

7. Causes of tire bubbling: cracks in the inner layer of tires cause gas to reach the surface through cracks and eventually cause the tires to “fire.”

The solution: It is best to change the tires in time, especially when driving long distances.

8. Reasons for inner wear of the tire: The inside of the tire is worn and the outer edge is burr-like. It is common for some old cars to have a bad suspension system, which causes the entire vehicle body to sink deep. This shows that the tire deformation, the symmetry of the two tires has been affected.

Solution: It is best to replace all parts such as shock absorbers and ball joints. If the cost is too high, you should first ask a professional repairman to adjust the front axle and tire angle.
