Driving more, tires will wear, this does not mean that we have a problem with driving, but normal driving is bound to happen. But a tire failure is dangerous. It can throw your car out of control or leave you in the middle of nowhere. Therefore, it is necessary to know the use of the tire, and determine whether the tire should be replaced according to the usual precursor.

1, tire tread pattern depth

The thickness of the tread pattern should be at least greater than 1.6mm, and if it is often driven on the wet road with low friction, it is better to ensure that the depth of the pattern is twice the above value. The simplest way is to use a 1 yuan coin to insert it into the tread gully along the direction of the top of the national emblem, because the distance between the edge of the coin and the top of the national emblem is between 1 and 2 mm, so if you can see the entire national emblem symbol at this time, the thickness of the tread pattern 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 groove vertically and longitudinally with the tread. When the tire is very new or the degree of wear is very low, the tire pattern wear indicator is almost not detected, but when the wear reaches a certain degree, these hidden indicator lines will be revealed. If almost all the indicators on the tire are clearly visible, it means that you need to replace the tire as soon as possible.

3, tire side wall cracks

In addition to possible problems on the tread, there will also be problems on the sidewall of the tire, such as small grooves indicating that there may be air leaks on the tire, and even cause a tire burst. So when the side wall cracks look severe, it is time to change the tire.

4. Bumps and bubbles appear on the tires

In some cases, the outer surface of the tire will not be strong enough, resulting in bumps and bubbles higher than the normal tire surface. This is like an aneurysm in a blood vessel, the tire is also faced with a similar situation, if you do not take the car to the repair shop in time to detect the tire failure, the lack of strength of the tread area is very likely to cause a sudden burst, if you can imagine the consequences on the highway.

5. Excessive vibration and jitter

A certain amount of jitter in the process of moving the vehicle is inevitable, especially in poor road conditions. When you have a certain amount of driving experience, you can judge what kind of jitter is within a reasonable range by feeling yourself, and what kind of jitter indicates that the vehicle has a fault. There are many causes of vehicle shaking, but some shaking may indicate that there are some problems inside the tire; Even if the tire is not the root cause of the vehicle shake, shake can damage the performance of the tire and cause tire problems before long. So if the shaking is more severe, or find a professional to check it.
