Suitable car tire pressure

1.According to the provisions and requirements of the international CBT2978-200 standard

Standard tires: 2.4-2.5 bar

Reinforced tires: 2.8-2.9ba

The maximum tire pressure: should not exceed 3.5bar

2.Other factors need to be referred

• Seasonal factors

a.Winter: Adjust the height of 0.2 bar appropriately according to the principle of standard tire pressure of the automobile tire.

• Load Capacity

1. No-load/Half-load: According to the lower limit of car tire pressure standard (the tire pressure of the vehicle label sticker can be used as the minimum tire pressure reference value).
2. Full load: Press the upper limit of the automobile tire pressure standard at full load (the maximum tire pressure on the tire label can be used as the reference for the theoretical maximum tire pressure).

• Tire pressure measurement environment

1. Hot tires: The tire pressures of the cold tires and hot tires are not the same and the difference between them is about 0.3 bar.
2. Cold tyres: At least after three hours’ parking or tires do not drive exceed 2 kilometers, if you can only measure tire pressure on hot tyres, please subtract the measured tyre pressure value by approximately 02.bar which is the tyre cooling inflation pressure.

• Tire condition

1. New tires: tire pressure can be increased by about 0.2 bar according to the tire pressure.
2. Properly reduce the tire pressure according to the automobile tire pressure standard. If the tire is badly worn, it should be based on the lower limit of the automobile tire pressure standard.
3. Soft tyres: Comfortable ring-shaped tyres are raised to about 0.2 bar in accordance with the lower limit of the standard tyre pressure.
4. Hard tires: that is handling tires, according to the lower limit of marked tire pressure.

• Traffic conditions

1. Larger bumps on the road surface should be adjusted to a tire pressure of 0.1-0.2 bar in accordance with the standard tire pressure.
2. The amplitude of the bump is small and can be ignored. It does not need to care.
3. Run long-distance high-speed, tire pressure can not be too low, properly adjust the tire pressure according to the lower limit of the standard tire pressure of about 0.2 bar.
