What is the appropriate tire pressure for cars in winter?

In winter, the tire pressure of the Pacific car network car is generally the most suitable at 230kPa. The tire pressure should not be too high in winter, just keep the standard tire pressure. Due to the principle that gas expands with heat and contracts with cold, it is normal that the tire pressure is 0. 1-0.2bar lower than that of standard tire in winter. Generally, it is normal for the tire pressure to be between 2.3 and 2.5.

The normal tire pressure value is 2.2 to 2.6. Excessive tire pressure will accelerate the wear of the middle part of the tire, resulting in uneven tire wear, smaller contact area between the tire and the road surface, and lower tire grip, which is not conducive to driving safety, especially on wet and slippery roads. In addition, if the tire pressure is too high, the tire will be too hard, its shock absorption effect will be worse, and the ride comfort will be worse. Too high tire pressure is easy to puncture in hot summer, and too low tire pressure will cause less wear in the middle of the tire. Both sides are badly worn, which also leads to uneven wear In addition, it also increases the rolling resistance of tires and increases the fuel consumption of vehicles. Moreover, low tire pressure is also easy to puncture. Because the tire pressure is too low, the tire is soft, and it is repeatedly extruded and deformed at high speed, generating a lot of heat, which leads to a puncture.

In addition, tire pressure is also related to factors such as season, road conditions and gestational age. Try to press the lower limit of standard tire pressure in summer. It's winter now, and it should be raised by 0.2bar on the basis of the standard air pressure of automobile tires. If you want to drive on a bumpy road, reduce the tire pressure by 0. 1-0.2bar according to the standard tire pressure.
