To what extent the tires are worn out and need to be replaced

Regularly inspect your vehicle's tires for wear mark baselines. When the outside of the tire reaches the baseline of tread wear, it is time to replace the tire. When the tire tread or edges are worn unevenly or the side of the tire is bulging, the tire should be replaced in time.

Many car owners think that after 40,000 to 50,000 kilometers, it is time to change the tires. In fact, there is a certain relationship between changing tires and the number of kilometers traveled by the vehicle, but the relationship is not very large. Generally, it is not a safe period for tires to run 50,000 kilometers.

Theoretically, tires should be replaced, but now it is rare for private cars to be replaced so early. One is that the owner loves the car, and the other is that the vehicle is in good condition. As long as the owner does not often accelerate, drag race, flick the tail, brake sharply, etc.

Tires with 7 80 thousand km, not much of a problem.

However, for some car owners who love road trips, they often choose to travel to the mountains. The uneven gravel roads in the mountains can cause a lot of damage to the tires of a car, especially if the sidewall is cut by a sharp object. Even if the tire wear is not serious, it is necessary to replace the tire in time to ensure driving safety.

Look** feel OK (pay attention to the third one, it seems that there is a scratch on the sidewall, as long as it does not hurt the cord layer, you can continue to use it, it is recommended to replace it with the rear tire, and at the same time you need to pay more attention to it, especially before preparing to run high speed and long distances, check whether there is any air leak to see if the damage to the tire has been aggravated), the tire can also continue to drive 1-2w kilometers, for reference.

When the tire pattern is worn to the limit, it needs to be replaced, the tire has been used for 6 years, even if the tire pattern is not worn to the limit, it needs to be replaced, the tread or side of the tire is seriously damaged, or the tire has more than 3 patches, and the tire surface is seriously eccentric.

The aging of tires has a great relationship with the environment, and the normal service life is about 6 years. And the harsh environment will accelerate this deadline. If you find that the tire has such a situation, then even if it is not 6 years, you must replace the tire as soon as possible, otherwise it will easily cause the consequences of a large puncture.

Tire wear precautions.

In order to reduce tire wear, the correct way to drive is to start driving, not too violent, so that the car starts slowly, smoothly and naturally without shaking, so as to avoid accelerated tread wear due to tire and ground dragging.

The correct way to drive downhill is to control the appropriate speed according to the size and length of the slope and the road surface. At the same time, keep a safe distance of more than 50 meters from the vehicle in front of you and drive on the right. When going uphill and downhill, you should use a low speed to pass, especially uphill, and you should pass in one go to avoid stopping halfway.

How many kilometers.

1. When the tire is worn to the wear limit mark, it must be stopped (that is, the tread depth is less than mm).

2. Tire aging (physical inspection and confirmation).

3. Tires with deformed tread or bead damage, tires damaged by sidewall crushed due to airless driving, and tires corroded by chemicals shall not continue to be used.

4. Bulging tires shall not continue to be used.

5. If other damage affects the safety of the tire, it shall not be used continuously.

1.Regularly check the baseline of the vehicle's tire wear marks. When the wear on the outside of the tire tread reaches the replacement baseline, the tire needs to be replaced. When the tire tread or edge is evenly worn, or the sidewall is bulging, the tire should be replaced in time.

2.After 100 kilometers of driving, it was time to change the tires. In fact, the number of kilometers traveled by a vehicle with a tire change is related, but it has a lot to do with it.

Running a one-kilometer tire is a safe period. Theoretically, tires should be replaced, but this is rarely done in private cars these days. The car cherishes the car, and secondly, the road condition of the vehicle is also better.

As long as the car keeps accelerating, racing, turning, braking, etc. With km tires, there is no problem.

But the modality is that for some cars who love road trips, they tend to choose to go to the mountains. The rough and uneven gravel roads in the mountains can cause a lot of damage to the tires of a car, especially if the sidewall is cut by a sharp object. Even if the tire is worn, the tire should be replaced in time to ensure driving safety.

One. The middle pattern of the tire is smoothed, which means that the tire pressure is too high. This can be the case with particularly wide tires.

If the tire has been hit with nitrogen, it is generally rarely ground in the middle, but if the air has been played, the water removal of the compressor is not good, and there is too much moisture in the air, and it is easy to have intermediate grinding.

Two. One side is smoothed, the other side is fine. Typical eccentric grinding.

In this case, there is a problem with the four-wheel alignment data, mainly because there is a problem with the toe-in, and it should be noted that it is not only the front wheel, but also the toe-in. Both the front and rear wheels have toe-in.

When the tires are eccentric, you can ventilate or redo the wheel alignment according to the situation.
