How to solve the low fetal pressure?

Due to the low temperature 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. But the air pressure of the tire should not be too high, otherwise the friction between the tire and the ground will be greatly reduced and the braking performance will be weakened. In winter, the tire pressure level should be increased or decreased according to the manufacturer's standards and effectively combined with the road surface.
