Tire pressure becomes lower in winter.

In winter, the tire pressure of cars tends to be lower. Because the temperature is lower in winter, the tire pressure will also be reduced due to the influence of thermal expansion and contraction, so there will be insufficient tire pressure. Due to the low temperature in winter, rubber tires become hard and brittle, and the friction coefficient will be reduced, which is easy to leak and puncture. Car owners are advised to check the tire pressure frequently. If there is something wrong with the tire, replace it in time.
