Tire pressure is too low or too high, will affect the life of the tire. If the tire pressure is too low, its radial deformation increases, excessive deformation on both sides of the tire wall, resulting in wear of the tire crown and shoulders, so that the temperature of the tire increases, will seriously reduce the life of the tire.
If the tire air pressure is too high, the tire rigidity increases, the distortion and the grounding area reduces, causes the tire tread middle the unit pressure to increase, the wear path intensifies. The central abrasion of the tire crown will affect the comfort and reduce the life of the tire. The test shows that if the air pressure is increased by 25% , the life of the tire will be shortened by about 30% .
