What is the best tire pressure for a car in winter?
The best car tire pressure in winter is 2.2 to 2.4 bar.
The appropriate car tire pressure in winter is 2.2 to 2.4 bar. The car tire pressure is the pressure of the air inside the tire. The level of tire pressure plays an important role in the performance and power of the car.
Tire pressure detection can be done by measuring the tire pressure with an instrument, visually checking the tire pressure, or consulting 4S staff. However, it should be noted that the visual method is not particularly accurate, and professionals should be consulted. If the tire pressure is too low, the adhesion area between the tire and the ground will increase, and the steering wheel will become heavy, which will affect driving; the tire will easily heat up and puncture; it will make the tire body larger, and cracks will easily appear on the inside and outside of the tire, accelerating rubber aging. Accelerates tire wear.
Damage caused by too high or too low tire pressure
Excessive tire pressure will increase wear in the middle part of the crown. Tire pressure will rise or fall with changes in air temperature and tire temperature. Generally, the tire pressure of cars and SUVs is around 2.3-2.5 when the car is cold.
Tire pressure is too low: Tire pressure that is too low or too high will affect the service life of the tire. If the tire pressure is too low, its radial deformation will increase, and both sides of the sidewall will be excessively deformed, causing wear on both shoulders of the crown and raising the temperature of the tire, which will seriously reduce the service life of the tire.
If the tire pressure is too high, the rigidity of the tire increases, the deformation and ground contact area decrease, which increases the unit pressure in the middle of the tread and intensifies wear. The central wear of the crown occurs, which affects comfort and reduces tire life.
When the car tire pressure is too high, it needs to be deflated. If there is an L-type tire pressure gauge, you can unscrew the tire valve cover, find the center core of the valve and press it lightly, and then While checking the tire pressure gauge, press the deflation valve and observe the number on the gauge until the tire pressure returns to normal.
If there is no special air release valve, you can only use the valve core wrench to deflate, or use a thin-pointed object like a pen to push the valve core, and then slowly release the air. However, in the end, It is best to equip the vehicle with a pressure gauge to avoid excessive deflation.
