When the weather is cold, the tire pressure becomes 124, but the tire is good. Why?

It is normal for tire pressure to decrease in cold weather, because automobile tires are made of rubber. In winter, tire rubber will harden a lot because of thermal expansion and cold contraction, while thermal expansion and cold contraction. The principle is that tires will expand when heated and contract when cooled. Therefore, it is normal to keep the tire at 2.2-2.5 bar in winter.

In addition, if the winter temperature in your area is lower than 6 degrees Celsius, it is recommended to replace the snow tires in winter; Because ordinary four-season tires will become very stiff in winter, the grip will decrease obviously, which will seriously affect the performance of brakes; It is recommended that you replace the snow tires in winter, which is safe and secure.

In short, no matter on any road surface, only when the tire is within the normal tire pressure range can the tire texture maintain a good working condition and provide a good grip. In addition, on wet or snowy roads, only normal tire pressure can obtain good acceleration braking performance.
