What is the appropriate tire pressure in winter?

In winter, the tire pressure is 2.5 to 2.8 bar.

It is good to have a higher tire pressure in winter. It is cold in winter, and the air pressure in winter should be raised appropriately. In winter, the tire pressure of a car is generally 2.5 to 2.8 bar. In order to ensure driving safety, when the temperature drops, you must carefully check the tires, often clean the inclusions on the tread, try to avoid using tires that have been patched for many times, and replace tires with different brands that are worn out.

In addition, having good driving habits can also reduce tire wear. For example, avoid starting too hard, turning sharply, braking suddenly, driving at high speed in areas with poor road conditions, getting on and off kerbs frequently, scraping obstacles when parking, etc.

If the calibrated standard tire pressure is 2.3bar, the tire pressure can be increased to 2.5bar in winter. Higher tire pressure in winter is beneficial to tires and reduces tire wear. But basically everything has two sides. When the tire pressure is high, the adhesion of the tire to the road surface becomes smaller accordingly. Therefore, if you encounter rain, snow or road icing, you can appropriately reduce the air pressure and improve the adhesion of the tire.

Preventive measures of tire pressure

The tire pressure should not be too high or too low, and it should be inflated according to the pressure specified by the manufacturer.

When the tire pressure is too low, the contact surface between the tire and the ground increases, which increases the rolling resistance of the tire and makes the temperature inside and outside the carcass rise sharply. The rubber material of the tire will soften the tread due to high temperature, which will lead to serious wear in the middle of the tire, reduce the contact area with the ground, extend the braking distance, and reduce the elasticity of the tire, leading to tire puncture.

When the tire pressure is too high, the tire cord will be stretched and deformed excessively, and the middle of the tread will bulge, resulting in serious wear in the middle of the tire; The contact area with the ground is reduced, the adhesion is reduced, the car is more likely to slip, and the braking distance will be extended. At the same time, the tire rigidity increases and the dynamic load of the wheel increases, which is easy to cause tire puncture.
