What is the tire pressure in winter?

Automobile tire pressure is generally 2.3 to 2.5 bar in winter.

The normal tire pressure value is 2.2 to 2.6. The tire pressure in winter should not be too high. Just keep the standard tire pressure. Due to the principle that gas expands with heat and contracts with cold, it is normal that the tire pressure is 0. 1-0.2bar lower than that of standard tire in winter. Generally, it is normal for the tire pressure to be between 2.3 and 2.5.

Influence of tire pressure

Air pressure is the key to tires. Too high or too low will shorten the service life of tires.

If the air pressure is too low, the deformation of the carcass will increase, and cracks will easily appear on the sidewall. At the same time, it will produce buckling movement, lead to excessive heating, promote rubber aging, tire cord fatigue and cord fracture. It will also increase the contact area of the tire and accelerate the wear of the shoulder.

If the air pressure is too high, the tire cord will be excessively stretched and deformed, and the elasticity of the carcass will decrease, which will increase the load when the car is running. Once hit, it will cause internal cracking and explosion. At the same time, too high air pressure will accelerate tire crown wear and reduce rolling resistance.
