Let me explain what tire pressure is.

Tire pressure, strictly speaking, refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car; engine damage leads to the end of the car's lifespan. Similarly, tire pressure is like the blood pressure of the car; its level plays a crucial role in the car's performance and power.
Many car tires nowadays are not inflated with air. For these tires, the required tire pressure is more stringent. In contrast, the pressure of inflated tires is related to seasonal changes. Furthermore, tire pressure is closely linked to vehicle performance, such as comfort and load capacity, and also affects tire lifespan.
Tire pressure is crucial; both excessively high and low pressure can shorten tire lifespan.
Low tire pressure can cause increased tire deformation, making the tire sidewalls more prone to cracks. It can also cause flexing movements, leading to excessive heat, which can accelerate rubber aging, fatigue of the cord layers, and breakage of the cords. In addition, it can increase the tire's contact area with the ground and accelerate tire shoulder wear.
Excessive tire pressure causes excessive stretching and deformation of the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving. This can lead to internal cracks and blowouts upon impact. Furthermore, excessive tire pressure accelerates tread wear and reduces puncture resistance.
