Is a Tire Pressure of 2.2 Normal?

[DiJohn]

A tire pressure of 2.2 is not normal and is slightly low. According to international standards and requirements: standard tires should have a pressure of 2.4 to 2.5 bar, reinforced tires should have a pressure of 2.8 to 2.9 bar, and the maximum pressure should not exceed 3.5 bar. In winter, it is advisable to increase the tire pressure by about 0.2 bar based on the standard tire pressure, while in summer, the lower limit of the standard tire pressure should be followed. Strictly speaking, tire pressure refers to the air pressure inside the tire. In terms of car maintenance, the engine is the heart of the car—damage to the engine can 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 car's performance and power.
