Is it normal for tire pressure to drop when the weather is cold?

When the weather is cold, tire pressure normally drops and gas expands with heat and contracts with cold. In winter, it is normal for tire pressure to decrease as temperatures drop.

Hazards of excessive tire pressure:

The friction and adhesion of the tires will decrease, affecting the braking effect;

Causing the steering wheel to vibrate and deflect, reducing the Driving comfort;

Accelerate the local wear of the tread pattern in the center of the tire and reduce the tire life;

The increased body vibration will indirectly affect the life of other components;

< p>The tire cord will be subjected to excessive stretching and deformation, the elasticity of the carcass will be reduced, and the load on the car will increase.

Rolling resistance is reduced. When encountering sharp objects such as nails and glass on the road, they can easily penetrate into the tire. The impact will cause internal cracking and explosion, leading to a tire blowout.

Hazards of low tire pressure:

The coefficient of friction with the road surface will increase, and fuel consumption will also increase.

Resulting in unfavorable driving safety factors such as a heavy steering wheel and easy deviation;

Increase the amount of movement of various parts of the tire, and excessive rolling will cause abnormal heating of the tire;

Curtain The role of the cord and rubber is reduced, causing delamination or excessive friction between the cord and the rim, causing bead damage and abnormal wear;

The friction between the tire and the ground doubles, the tire temperature rises sharply, and the tire becomes deformed. Soft, the strength drops sharply. If the vehicle travels at high speed, it may cause a tire blowout;

The deformation of the carcass will increase, cracks will easily appear on the sidewalls, and buckling movement will occur at the same time, leading to tire overheating, rubber aging, tire cord fatigue, and cord fatigue. Breakage will also increase the tire contact area and accelerate tire shoulder wear.
