Diligently check the surface of the tire to ensure it is clean. The driver's friends should develop habits of checking the cars regularly. Regularly check the grooves in the tires for stones and other foreign objects. Also pay attention to the warranty period of the tires. The service life of the tires is generally 2-3 years or 6-. About 100,000 kilometers. When the pattern depth is 1.6mm (minimum wear), the tire should be replaced immediately. For tires that exceed the shelf life (especially for spare tires, the life expectancy of the spare tire is approximately 3 years), the overall performance has been reduced. .
