If the car is driven more, the tyres 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, tire tread pattern depth
The thickness of the tread pattern is at least greater than 1.6mm. 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 tires are very new or have a low degree of wear, the tread pattern wear indicator lines are barely noticeable, but when the wear reaches a certain level, these hidden indicator lines 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 crack
In addition to problems that may occur on the tread, tire sidewalls can also have problems. For example, small grooves indicate that there may be cracks in the tires on the tires and even punctures. So when the tire sidewall cracks look terrible, change the tires.
4, there is raised on the tire and foaming
In some cases, the outer surface of the tire will not be strong enough to cause bumps and blisters above the normal tire surface. This is like an aneurysm in a blood vessel. The tire is also facing a similar situation. If you fail to send the vehicle to the repair shop to check the tire failure, the area with insufficient strength on the tread surface is likely to cause a sudden burst. If you are at high speed, you can imagine the consequences.
5, excessive vibration and jitters
It is unavoidable that a certain amount of dithering occurs during the forward movement of the vehicle, especially under poor road conditions. When you have a certain driving experience, you can feel what kind of jitters is within a reasonable range and how the jitters indicate that the vehicle is faulty. There are many incentives for vehicle vibration, but some jitters may indicate that there are certain problems inside the tire; even if the tire is not the root cause of vehicle vibration, the vibration will also impair the performance of the tire and cause tire problems soon. So if the jitters are terrible, check with a professional.
