What is the best tire pressure for winter?
2 Answers
On the basis of standard air pressure, it is appropriate to increase by about 0.2bar. The following are relevant information about tire pressure: 1. The standard tire pressure for a car can be found in the car's maintenance manual. Some cars also have reference values for standard tire pressure on the label next to the driver's door (near the B-pillar), or even on the fuel tank cap. Adjusting the car's tire pressure is not a specific value; it also depends on the usual driving environment and habits. If you cannot adjust it yourself, you can go to a related 4S store for adjustment, which can better improve driving safety. 2. If the tire pressure is too high, it will increase the tire's friction and reduce the tire's adhesion. In emergency situations, the braking effect will be poor, and driving safety cannot be guaranteed. You may also feel vibration in the steering wheel while driving, accompanied by phenomena such as deviation, which will reduce driving comfort.
Actually, the ideal tire pressure in winter isn't a fixed value - it depends on specific conditions. Through years of driving experience, I've learned that tire pressure should follow the vehicle's specifications. There's always a label on the door jamb showing the manufacturer's recommended value, which is the golden standard. When winter temperatures drop, tire pressure automatically decreases. I usually measure the pressure when the tires are cold, then inflate to 0.1-0.2 above the recommended value, but never exceeding the maximum pressure marked on the tire sidewall. I always check before long trips because insufficient pressure makes the car particularly prone to losing control when turning on snow, and failing to brake on ice is terrifying. For vehicles parked outdoors long-term, it's best to use a temperature-compensated tire gauge for weekly checks.
