What is the suitable tire pressure in winter?
2 Answers
In winter, a tire pressure of 2.2~2.5 is generally suitable. Here are some details about winter tire pressure: 1. Cold tire pressure: A cold tire pressure between 2.2~2.5 is normal. It is usually recommended to maintain a cold tire pressure of 2.5, as this can result in lower fuel consumption, and during high-speed driving, the tire pressure can be kept within the safe range of up to 3.0. The required tire pressure for the same tire may vary when installed on different vehicle models. 2. Vehicle model: The standard tire pressure for each vehicle model is indicated in the user manual, on the inside of the fuel filler cap, or below the B-pillar on the front passenger side. Although manufacturers provide the optimal tire pressure values, adjustments should be made according to temperature changes.
My experience is that tire pressure should be about 0.1 to 0.2 bar higher in winter than in summer, as the air inside tires contracts when it's cold. I just measured my car's tires the day before yesterday, and inflating them to 2.5 bar now seems just right. It's especially important to pay attention when parking in an open-air parking lot—it's best to check the tire pressure before driving off in the morning. If you're going on a long trip in snowy conditions, you need to be even more careful; insufficient tire pressure can easily cause the wheels to slip. Two years ago, I almost rear-ended someone at an icy intersection because I wasn't paying attention to this. Every two weeks, I use a tire pressure gauge to measure the pressure when the car is cold, and if it's below the value on the car's label, I go to inflate them immediately. I've been using this simple method for maintenance for five or six years now, and my tires have never had any issues.
