How are your car tires? Do you pay attention to frequent viewing? Don't forget about the status of car tires. In case of a serious incident.
The four wheels of the car. Including spare tires. Be sure to check regularly every month. When checking. Observe the tire surface for cracks or scratches at the same time. It is also best to wear gloves and reach inside the tire to 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 that it should be repaired.
1, the outer edge of the cause of wear
If observed along the direction of travel, there is greater wear on the outside edge of the tire, indicating that the tire is often under-inflated, ie, the pressure is insufficient.
Solution Check several times more tire pressure. If possible, inflate by the "highway" standard, which is an additional 30,000 Pa over normal standards. Furthermore, it is generally believed that since the tire is under-inflated, it is conducive to driving in snow and sand, as well as on wet ground. It should be noted that under-inflated tires are very unfavorable for rainy days and the grip will be significantly reduced.
2, convex and corrugated wear causes
If it is found that both sides of the tire land are convex wear, and the tire periphery is also corrugated wear, indicating that the car's shock absorbers, bearings and ball joints and other components wear more serious.
Solution Since replacement of new tires is expensive, it is recommended that you replace the tires. First check the wear of the suspension system and replace worn parts. Otherwise, even if you change the tires will not help.
3, the reasons for uniform surface wear
Uniform wear of tires is normal. Each department will have a corresponding performance. Once the pattern has dried. Explain that the life of the tire is exhausted. It must be replaced. In addition, the pattern also has the effect of dissipating water in the road area and is therefore an important part of maintaining the car's grip.
Solution Do not make your own tread pattern. 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. Of course, there will be differences in the degree of wear. But notice. The difference in wear of different tyres on the same axle must not exceed 5 mm.
4. Reasons for "dark injuries" in the tire
After the vehicle has collided with a hard object (eg, hit the edge of a sidewalk). Or after abortion, the tire rubber layer will have serious scratches, affecting the degree of sealing.
The solution is in this situation. Tire leaks and breaks. If the wound is small, it can be repaired, and it can be used on a regular basis. However, if you want to travel long distances, you must replace it immediately.
5, the central part of the cause of wear
If it is found that the central area of ​​the tire is heavily worn out, this indicates that the tire is often over-inflated. This is also not conducive to the maintenance of the tire, but accelerated the tire's wear.
Solution First, be sure to check the accuracy of the pressure gauge and adjust the pressure. Notice. Only when driving at high speed or on a heavy load. It is necessary to inflate the tire too much, but it is not necessary under normal conditions.
6, the reasons for the tire side crack
Due to poor maintenance. Or driving on a rocky road and on a construction site, so that hard objects come in contact with the tires, causing damage to the inner layers of the tires under heavy pressure.
The solution must be immediate, if the repairs are not too expensive. Repair is better, or tires will have to be replaced. Although tires now use new technologies, they are also more delicate and need to be properly maintained.
7, tire bubble causes
Blisters appear on the side of the tire. This is because there is a crack in the inner layer of the tire, which causes the gas to reach the surface through the crack, and eventually causes the tire to "fire."
The solution is not to think that it is possible to fix things and patching rubber does not last long. Especially when driving long distances, it is best to change tires in time.
8, tire inner wear causes
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 deformation of the tire and the symmetry of the two tires have been affected.
Solution If conditional. It is best to replace the shock absorbers, ball joints, and Other Accessories. However, if the cost is too high, consider asking a professional mechanic to adjust the front axle and the tire angle.
9. Causes of local tire wear
If there is only a large area of ​​wear on the surface of the tire, it means that it was caused by the wheel when it was braked. If there are two pieces of wear on the front and rear wheels, it means there is a problem with the drum brake.
Solution In this case, the tire must be replaced anyway. In order to cope with emergencies, of course, old tires can be temporarily transferred to the rear wheels to ensure safety.
