Will tire pressure decrease when the temperature is low?

If the temperature is low, tire pressure will decrease. Because the temperature is low in winter, tire pressure will also decrease due to thermal expansion and contraction. At this time, if the tire pressure is increased improperly, it will not only increase the car's fuel consumption, but also accelerate the wear of the car's tires. In winter, rubber will harden and become more brittle, and the friction coefficient will decrease. This requires that the tire pressure should not be too high, but it should not be too low. If the outside temperature is low and the tire pressure is too low, soft tires will accelerate aging and aggravate the friction between the tire and the ground. Contact accelerates friction and reduces tire life. So tire maintenance is also very important. Choose better winter tires for replacement. Due to the cold weather, tire rubber will be harder than in the summer. Even though many cars are equipped with all-season tires, icy and slippery roads can test the tire's grip. For driving safety, it is necessary to replace winter tires. Pay attention to the vehicle's tire pressure and ensure that the front and rear tire treads on each side are in complete contact with the ground to achieve the best grip. At the same time, appropriate tire pressure can reduce road vibration and increase driving comfort.
