What is the appropriate tire pressure for cars in winter?
2 Answers
Winter tire pressure should be around 2.6-2.7bar. According to the international GBT2978-2008 standard, the standard tire pressure is 2.4-2.5bar. Based on the principle of thermal expansion and contraction, winter tire pressure should be adjusted slightly higher than the standard tire pressure by about 0.2bar. Additional information: Other factors to consider for car tire pressure: 1. Seasonal factors: In winter, adjust the tire pressure slightly higher than the standard by about 0.2bar. In summer, use the lower limit of the standard tire pressure. If the car is parked outdoors in summer, the pressure can generally be about 0.1bar lower than the standard to avoid tire blowouts due to high temperatures. 2. Tire condition: For new tires, the pressure can be set slightly higher than the standard by about 0.2bar. For old tires, adjust the pressure slightly lower according to the standard. If the tires are severely worn, use the lower limit of the standard tire pressure.
I see many people neglecting tire pressure in winter, which is unacceptable. Low tire pressure makes it easy to skid on snow, lose grip on the road, and lose control when braking. Having driven for decades, I know that tire pressure naturally drops a bit in winter due to the rapid temperature drop, but never add air randomly. The standard label in the car is usually located on the driver's door edge or glove compartment, showing the normal tire pressure range, such as between 32 and 35 psi. Checking it when the car is cold in the morning before heading out is the most accurate—just press with your finger or buy a small tire pressure gauge. Overinflating makes the ride uncomfortably bumpy, while underinflation wears out the tires faster and shortens their lifespan. Once, I forgot to check and had a blowout on the highway—how dangerous! I remind everyone to check once a month for safety.
