What is the air pressure of the car in winter?

The calibrated standard tire pressure is 2.3bar, which can be increased to 2.5bar in winter. Higher tire pressure in winter is beneficial to tires and reduces tire wear. But everything basically has two sides, and the higher the tire pressure, the smaller the adhesion of the tire to the road surface. Therefore, if you encounter rain, snow or ice on the road, you can appropriately reduce the air pressure and improve the adhesion of the tire.

In fact, whether it is winter or summer, we basically don't have to deliberately raise or lower the tire pressure. As long as we drive according to the calibrated standard tire pressure, there will be no big problem. The standard tire pressure of each vehicle can be checked at the fuel filler. The first line of the tire pressure table is the standard tire pressure, and the standard tire pressure of most family cars is 2.3bar.

Tire pressure can also be appropriately increased according to the load. When the load is heavy, the front tire pressure can be adjusted to 2.4bar and the rear tire pressure can be adjusted to 2.6bar.

Extended data:

Check the tire pressure regularly to ensure safety;

1. Observe the tire condition before going out. Radial tires-that is, low-pressure tires, as long as the flatness is not too low, it is normal to feel great elasticity under the pedal. High pressure tire-bias tire with inner tube. From the front, the shoulder position of the tire is not prominent, which is commonly known as "no cheeks". Seen from the side, the contact area with the ground is almost normal.

2. Pay attention to the friction between the tire and the ground when driving, feel the buffering force when the road surface is not very flat, and feel whether the acceleration has changed compared with usual when refueling. These are all accumulated experiences.

3. Under normal circumstances, go to a professional tire repair shop every week to check and replenish the air pressure.
