What is the Suitable Tire Pressure in Winter?
1 Answers
According to the provisions and requirements of the international GBT2978-2008 standard, the tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: should not exceed 3.5bar. In winter, the tire pressure should be based on the standard tire pressure of the car and appropriately increased by about 0.2bar. In summer, when the car is parked outdoors, the pressure can generally be about 0.1bar lower than the standard to avoid tire blowouts due to high temperatures. Other factors affecting tire pressure: Empty/half load: Use the lower limit of the standard tire pressure (the tire pressure indicated on the vehicle sticker can be used as a reference for the minimum tire pressure). Full load: When fully loaded, use the upper limit of the standard tire pressure (the maximum tire pressure indicated on the tire can be used as a reference for the theoretical maximum tire pressure). Hot tires: The tire pressure of cold and hot tires is different, so be careful when measuring. The difference is about 0.3bar. Cold tires: After parking for at least three hours or if the tires have not been driven more than 2 kilometers. If you can only measure the tire pressure when the tires are hot, subtract approximately 0.2bar from the measured tire pressure to get the cooled inflation pressure.
