tire pressure, strictly refers to the pressure of air inside the tire. In car maintenance, the engine is the heart of the car. The damage to the engine will lead to the exhaustion of the car's life. The tire pressure is the blood pressure of the car. The level of the tire pressure plays a crucial role in the performance and power of the car.
air pressure is the life gate of the tire. Too high and too low will shorten the service life of the tire. If the air pressure is too low, the carcass will deform and increase the deformation, and cracks will easily appear on the sidewall, and flexural movement will occur, resulting in excessive heating, causing rubber aging, fatigue of the ply, breaking the cord, and increasing the tire grounding area, accelerating the wear of shoulders and . If the air pressure is too high, the tire cord will be subjected to excessive expansion and deformation, and the carcass elasticity will decrease, which will increase the load on the car during driving. If it is impacted, internal cracks and blasts will occur. At the same time, the air pressure will be too high, which will accelerate the wear of the crown and reduce the rolling resistance.
Generally speaking, the normal tire pressure is subject to the recommended value of the vehicle manufacturer. The tire pressure standard is related to the tire type and vehicle model. Different models have different weight, height and tire size, and the required tire pressure is also different. The tire pressure of the standard tire is 240kpa-250kpa, and the tire pressure of the enhanced tire is 280kpa-290kpa. Moreover, the tire pressures of cold tires and hot tires are also different. The tire pressure of hot tires is about 20kpa higher than the cold tires. The recommended value of the manufacturer is the cold tire pressure value. The tire pressure in the cold car is around 230kpa-250kpa, but the specific tire pressure marked by each car shall prevail.
