Tire pressure, in the strict sense refers to the tire internal air pressure. In the car maintenance engine is the heart of the car, the engine damage will lead to the depletion of car life, then the tire pressure is the car's blood pressure, tire pressure on the level of performance and power of the car has a crucial role.
Now many tires are not filled with air. For these tires, tire pressure requirements are more stringent. The tires filled with air, and the four seasons transform a relationship. And the tire pressure and the performance of the car are closely linked, such as comfort and carrying capacity, will affect the tire life.
Pneumatic pressure is the lifeblood of tires, too high and too low will shorten the tire life.
Too low pressure will increase the deformation of the carcass, the sidewall prone to cracks at the same time produce flexion movement, resulting in excessive heat, to promote rubber aging, ply fatigue, broken cord, tire tread area will increase, Shoulder wear.
Excessive air pressure will cause excessive deformation of the tire cord, the carcass elasticity decreased, so that the car in the load by the increase in the case of shock will have a crack and blasting, while high pressure will accelerate the crown Wear, and to reduce the rolling resistance.
