What is the appropriate tire pressure in winter?
2 Answers
Winter tire pressure is appropriate between 2.6bar and 2.7bar. If the tire pressure is too high, it will reduce the contact area between the tire and the ground, leading to poor tire grip. If the tire pressure is too low, the tire may experience wave deformation during high-speed driving, which will reduce the tire's service life and increase the risk of a blowout. Tire pressure refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and engine damage will lead to the end of the car's life. Similarly, tire pressure is the blood pressure of the car, and the level of tire pressure plays a very important role in the performance and power of the car.
When I first got on the highway, I noticed the tires were a bit flat, so I did some research on this issue. Simply put, winter tire pressure is usually slightly higher than in summer, with the most stable range being around 2.2-2.5 bar. Last month, I actually tested this—after leaving the car overnight, the cold tire pressure was 2.0 bar in the morning, and it dropped to 1.8 bar after just two kilometers of driving. So now I make it a habit to check every two weeks, measuring before driving in the morning for the most accurate reading. Don’t rely solely on the onboard monitoring system; keep a cheap mechanical tire pressure gauge in the glove box as a backup. When inflating, remember to go 0.2 bar above the manufacturer’s recommended value, and top up a bit more when a cold snap hits—this ensures enough grip on icy or snowy roads.
