If the car is driven too much, the tires will wear out. This does not mean that there is a problem with our driving, but something that will inevitably happen in normal driving. Pneumatic tire picker, but tire failure is very dangerous, it may cause your car to lose control, or it may throw you in a ghost place that can't reach the village or the shop. Therefore, it is necessary to know the usage of the tires and judge whether it is time to replace the tires according to the usual signs.

1. Tire tread pattern depth

The thickness of the tread pattern must be at least 1.6mm. If you often drive on wet and slippery roads with low friction, it is best to ensure that the tread depth is twice the above value. The easiest way is to use a 1 yuan coin and insert it into the tread groove along the top of the national emblem. Because the distance from the edge of the coin to the top of the national emblem is between 1 and 2 mm, if you can still see the entire national emblem at this time , Indicating that the tread pattern thickness is insufficient.

2. Tread pattern wear indicator line

The tread pattern wear indicator line is a flat rubber strip which is embedded in the tread gully perpendicular to the longitudinal direction of the tread. When the tire is very new or the degree of wear is very low, the tire pattern wear indicator lines are almost undetectable, but when the wear reaches a certain level, these hidden indicator lines appear. If almost all the indicator lines on the tire are clearly visible, it means you need to replace the tire as soon as possible.

3. Cracks in the tire sidewall

In addition to possible problems on the tread, there are also problems with the sidewall of the tire. For example, small grooves indicate that there may be air leaks on the tire, or even a flat tire. So when the tire sidewall cracks seem to be severe, change the tire quickly.

4. Bumps and blisters appear on the tires

In some cases, the outer surface of the tire may not have enough strength, resulting in bumps and blisters that are higher than the normal tire surface. This is like an aneurysm in a blood vessel, and tires face similar conditions. If you fail to send the vehicle to the repair shop in time to detect tire failure, the area with insufficient strength on the tread is likely to cause a sudden burst. You can imagine the consequences.

5. Excessive vibration and jitter
A certain amount of jitter is inevitable when the vehicle is moving forward, especially under poor road conditions. When you have a certain driving experience, you can judge by yourself what kind of jitter is within a reasonable range, and what kind of jitter indicates that the vehicle is malfunctioning. There are many causes of vehicle shake, but some of the shake may indicate some problems inside the tire; even if the tire is not the root cause of the vehicle shake, the shake will damage the performance of the tire and cause tire problems soon. So if the jitter is severe, you should find a professional to check it.
