Recently, Michelin Tire held a "tire knowledge training" event in Shanghai. At the event, Michelin tire experts taught the tire knowledge, tire maintenance methods and tire testing methods to many participants. Many owners believe that the tire pressure must be sufficient, otherwise it will affect the safety and fuel consumption. Michelin tire experts said that when the tire pressure is too full, the middle part of the tire is raised, so that the tire grip force is reduced, and will cause part of the tire to wear, thereby reducing tire life. In addition, the owner of the vehicle should always perform air pressure correction on the tire. If the air pressure drops too fast, it should be repaired or replaced in time. In addition, in order to prevent tire aging damage, should try to keep the tire away from oil and acid.
