If the car is driven more, the tires will wear out. This does not mean that we have problems with driving, but it is inevitable that normal driving will happen. However, tire failure is very dangerous. It may make your car out of control. It may also throw you in a ghost place that is not in front of the village. Therefore, it is necessary to make clear the use of the tires and to judge whether or not to replace the tires according to the usual precursors.
1. The depth of the tread pattern of the tire tread should be at least 1.6 mm thick. If you often run on a slippery road with low friction, it is best to ensure that the pattern depth is twice the above value. The easiest way is to use a one-dollar coin, which is inserted 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, so if you can still see the entire emblem , indicating that the thickness of the tread pattern is already insufficient.
2. Tread pattern wear indicator line The tread pattern wear indicator line is a flat rubber strip that is vertically embedded in the tread groove in the longitudinal direction of the tread. When the tire is very new or has a low degree of wear, the tread pattern wear indicator is barely noticeable, but when the wear reaches a certain level, these hidden indicators appear. If almost all indicators on the tire are clearly visible, it means that you need to replace the tire as soon as possible.
3, tire sidewall cracks in addition to the tread may be a problem, the tire sidewalls will also have problems, such as small grooves indicate that the tire may leak cracks, and even lead to puncture. So when the tire sidewall cracks look terrible, change the tires.
4. Embossing and blistering of the tire In some cases, the outer surface of the tire will not be strong enough to cause protrusion and blistering above the normal tire surface. This is like an aneurysm in a blood vessel. The tire is also facing a similar situation. If you do not promptly send the vehicle to a repair shop to detect the tire failure, the area with insufficient strength in the tread is likely to cause a sudden burst if it is at a high speed. I can imagine the consequences.
5. Excessive vibration and shaking A certain amount of jitter during the forward movement of the vehicle is unavoidable, especially under poor road conditions. When you have a certain driving experience, you can feel what kind of vibration is within a reasonable range and how the jitters indicate that the vehicle is faulty. There are many incentives for vehicle jitter, but some jitter may indicate that there are certain problems inside the tire; even if the tire is not the root cause of vehicle vibration, the jitter will also impair the performance of the tire and cause tire problems soon. So if the jitters are terrible, check with a professional.
