Normally used tires are replaced with 50,000 to 50,000 kilometers of ordinary tires, and 60,000 to 80,000 kilometers of high-quality tires. The production year and cycle of the tire are on the side wall of the tire. The service life of the tire should not exceed 4 years, otherwise the tire will age.

2. How often should car tires be replaced? According to the wear of the tires and the shelf life of the tires, the use of tires generally should not exceed 3 years, and the mileage should not exceed 60,000 kilometers.
