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

When the weather is cold, the tire pressure will decrease.

When the weather gets cold, the tire pressure is too low due to thermal expansion and contraction. According to the situation at that time, if the weather turns cold for only a short time, there is no need to inflate, but when the weather gets warmer, the tire pressure will rise. If the weather is cold for a long time, you can inflate it properly to keep the tire pressure within the normal range.

Because the tire is the only part that directly touches the ground, it will affect the driving stability and safety factor of the car. Tire pressure is an important parameter of tire, which should not be too high or too low.

Brief introduction of tire pressure

Strictly speaking, it refers to the pressure of air inside the tire. Now, many tires are not inflated. For these tires, the tire pressure requirements are strict. Inflated tires are related to seasonal changes. Moreover, the tire pressure is closely related to the comfort and bearing capacity of the car, which will also affect the tire life.

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