Is 250 car tire pressure normal in winter?

The normal tire pressure of a car is about 2.3. The tire pressure in summer should be relatively low, because the temperature in summer is high and the tires are easy to heat up. If the tire pressure is high, it will easily cause a puncture. In winter, the tire pressure should be normal. If it is too high, the grip will not be enough and it is easy to slip; if it is too low, the grip will be enough. , but due to low tire pressure, it will cause premature aging on both sides of the tire and affect the service life of the tire.

Low or too low tire pressure will deform the sidewall, which will not only increase fuel consumption but also increase tire wear. Generally speaking, based on the principle of thermal expansion and contraction, the tire pressure in summer can be 0.1-0.2bar lower than the reference value in the manual, and in winter it can be 0.1-0.2bar higher.

Since the suspension and gravity distribution of different cars are different, it is best to adjust the tire pressure of the front and rear wheels according to the instructions. Normally, when the car is cold, the front tires should be maintained at 220-230. , and the rear tire should be kept at 240-250 which is best.

The most standard tire pressure value can be found on the tire pressure label located on the driver's side front door frame, which indicates the original tires and the corresponding tire pressure. Tire pressure data refers to cold tire pressure. It is suitable for both summer and winter tires.

Check cold tire pressure at least monthly and before any long journey. Don't forget the spare tire, be sure to inflate it to the full specified pressure. If the tire pressure is too low, it can cause the tire to heat up significantly and cause internal damage, leading to tread delamination and even a tire blowout at high speeds.
