What is the optimal standard for car tire pressure?

[Lawson]

2.3-2.5 bar is the most suitable. Introduction to tire pressure: Tire pressure, strictly speaking, refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and its damage will lead to the end of the car's life. Similarly, tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the performance and power of the car. Effects of excessive tire pressure: Driving with excessively high tire pressure will reduce the tire's shock absorption effect, thereby increasing the burden on the vehicle's shock absorption system. Over time, it will cause damage to the engine chassis and suspension system. Uneven tire pressure can also easily cause braking deviation, increasing the wear on the suspension system. TPMS (Tire Pressure Monitoring System) can monitor any tire at any time, preventing the above phenomena and reducing the wear on the suspension system.
