The tire is worn to the wear mark and must be replaced. Tire replacement standard: Rubber has a certain service life. Generally speaking, the service life of automobile tires is about 3-5 years. Because the tire is exposed to the sun and rain for a long time, the rubber will gradually age, and the strength of the aging tire will become lower. Therefore, when the tire reaches its service life, it should be replaced in time.
