Maintenance of tires
The tire replacement cycle is generally about 2 to 3 years or 6 to 65,438+million kilometers. Of course, different brands may have different service lives. After all, the requirements for tires are slightly different. However, it is definitely not enough to decide the replacement time only by a numerical value, and ultimately it should be decided according to the real situation of the tire. If one of the following situations occurs, there is a certain safety hazard, and it is necessary to replace the new tire in time.
The most direct way to judge the degree of wear is to observe the degree of wear of tires, and almost every tire will have wear marks. The wear mark height of ordinary car tires is 1.6 mm, which is also the legal minimum groove depth of tires, and the wear mark height of truck tires is 2.4 mm If the wear mark is found to be as flush as the tread, it means that the tires are almost worn and should be replaced in time.
