Will the tire pressure decrease when the temperature is low?

If the temperature is low, the tire pressure will decrease. Because the temperature is low in winter, the tire pressure will also decrease due to the influence of thermal expansion and cold contraction. At this time, if the tire pressure is improperly increased, it will not only increase the fuel consumption of the car, but also accelerate the wear of the car tires. In winter, rubber will become hard and brittle, and the friction coefficient will decrease, which requires that the tire pressure should not be too high, but not too low. If the outside temperature is low and the tire pressure is too low, the soft tire will accelerate the aging, intensify the contact between the tire and the ground, accelerate the friction and reduce the tire life. So tire maintenance is also very important. Choose better winter tires for replacement. Because of the cold weather, tire rubber will be harder than in summer. Even if many cars are equipped with four-season tires, the frozen and slippery road will test the grip of the tires. In order to drive safely, it is necessary to replace winter tires. Pay attention to the tire pressure of the vehicle and ensure that the front and rear tire treads on each side completely touch the ground to achieve the best grip effect. At the same time, proper tire pressure can reduce road vibration and increase driving comfort.
