1. Carry out overall cleaning of the car, especially the key cleaning of the tires. If the tire surface is covered with mud, it is easy to cover up the scars on the tread. The cleaning is to check whether the tires have sand, cuts, bumps, etc. If the tire is found to be broken, it should be replaced immediately.
2. If the tires are found to have serious wear and tear, it will reduce the braking force of the car. To prevent such situations, it is best to replace them in time.
3. If the tire valve is found to be rubber during the inspection, when the rubber turns dark red, it indicates that the valve has been aged and good air tightness cannot be guaranteed. It is best to replace.
