What is the standard tire pressure for cars in winter?
2 Answers
The standard tire pressure for cars in winter is between 2.5 and 2.7 bar. Precautions for adjusting tire pressure during inflation include: 1. Check the pressure multiple times during inflation to avoid over-inflation, which may cause tire bursts; 2. After stopping the vehicle, wait for the tires to cool down before inflating; 3. Inspect the valve stem before inflating; 4. Ensure that the air being pumped in does not contain moisture or oil to prevent deterioration and damage to the inner tube rubber; 5. Avoid exceeding the standard tire pressure value, as it may cause excessive stretching of the cords, leading to reduced strength; 6. After inflation, check for any leaks at the valve stem and tighten it to prevent dirt from entering. Tire pressure refers to the air pressure inside the tire, which affects the comfort and handling stability of the vehicle.
Having driven for many years, I know winter tire pressure is crucial. When temperatures drop, the air contracts, causing tire pressure to naturally decrease, so it's safer to adjust it slightly higher. For passenger cars, the standard tire pressure can be found on the label on the side of the front passenger door, usually ranging from 30 to 35 PSI. In winter, it's recommended to add an extra 2 to 4 PSI, keeping it between 32 and 37. If the pressure is too low, tires become stiff, reducing grip on snow and ice, increasing braking distance, and raising the risk of accidents. Proper tire pressure also saves fuel by reducing rolling resistance. Too high, and you risk a blowout; too low, and you damage tire longevity. I always check my tires in the morning when they're cold, using a simple tire pressure gauge—it's a habit that prioritizes safety. Don’t forget to adjust the spare tire as well, and check it before winter trips for peace of mind.
