For driving safety, the tire pressure setting of the car will be determined by the car company after many road experiments to ensure the best safety and fuel economy. It varies depending on the temperature, road conditions, and the environment in which it is used.
The setting of automobile tire pressure mainly follows the international GBT2978-2008 standard
Standard tires: 24-2.5bar。
Reinforced tires: 28-2.9bar。
The maximum air pressure of the tire should not be greater than 35bar。
Considering the influence of seasonal temperature difference on tire pressure, the tire pressure of some heavy-duty vehicles should be adjusted accordingly.
Winter: Adjust the standard air pressure of automobile tires by 0About 2bar.
Summer: according to the lower limit of the standard air pressure of automobile tires. In summer, the car is parked in the open air, and the air pressure can generally be 0 lower than the standardAbout 1bar to avoid a puncture in the heat.
In addition, when different loading loads:
No load Half load: according to the lower limit of the car tire pressure standard (the tire pressure on the vehicle labeling sticker can be used as the minimum tire pressure reference value).
Full load: At full load, according to the upper limit of the standard tire pressure of the car (the maximum tire pressure value on the tire label can be used as a reference for the theoretical maximum tire pressure).
When driving in different road conditions:
The road surface with a large bump is appropriately adjusted to reduce the tire pressure by 0 according to the standard air pressure of the automobile tire1-0.2bar。
Running long-distance and high-speed, the tire pressure should not be too low, and the tire pressure should be increased by 0 according to the lower limit of the standard air pressure of the automobile tireAbout 2bar.
According to the condition of the tires in old and new:
New tires: The tire pressure can be increased by 0 according to the standard air pressure of automobile tiresAbout 2bar.
Old tires: Appropriately reduce the tire pressure according to the automobile tire pressure standard, and if the wear is serious, the lower limit of the automobile tire pressure standard shall be pressed.
Soft tires: tires with comfort patterns, which are appropriately adjusted by 0About 2bar.
Hard tires: i.e., steerable tread tires, according to the lower limit of the standard tire pressure.
