The simplest and most direct method is to look at the wear marks on the tire surface. Many people don't know that there is a wear limit mark at the bottom of each groove on the tread of any brand of tire, and the height (thickness) of the wear mark on general car tires is about 1.6mm. So, when the tread pattern on the tire is worn to a height close to the mark, it means it's time to replace the tire.

Some people may think that as long as the tire is not broken, even if the pattern is almost worn out, it can still be used, after all, the price of tires is not cheap. But in fact, this is very dangerous. When encountering wet and slippery road surfaces, the tread pattern cannot completely drain the accumulated water under the tire, which can easily lead to vehicle loss of control. So it goes without saying whether money or life is more important, right?

In addition, observe the tread and tread patterns of the tire. If cracks appear, it indicates that the tire has aged severely. Although the mileage or usage time after replacing the tire is not long, it must be replaced in a timely manner. Otherwise, the aging tire may cause blowouts due to weakened sidewall strength and increased temperature during high-speed driving, putting you in danger.

The main material of tires is rubber, and any rubber will age. According to experts, the lifespan of a typical tire is between 2 years or 60000 to 80000 kilometers, but in reality, it still depends on the situation. In fact, a 2-year deadline may be too fast for some people who use their cars less, and I can understand that the high cost of using a car is indeed a headache.

But don't worry, the 2 years we mentioned above is a general "official" term. If you don't use the car frequently and the environment is not too harsh, such as parking indoors for a long time with good temperature, the normal use of tires for 3 to 4 years should not be a problem. Of course, the premise is to check diligently and use them with care.

In addition, appropriate tire pressure can also help improve the lifespan of tires. In fact, the appropriate tire pressure for each vehicle is indicated on the inside of the door, and the standard tire pressure generally depends on the size, dimensions, and weight of the vehicle. Of course, in some special road conditions, tire pressure can be fine tuned.
