When do car tires inflate?

If the air pressure does not reach the standard tire pressure, it can be inflated. You should check the tire pressure at least once a month or before each long trip, including the spare tire.

Check the tire pressure when it is cold. In addition, check the tire pressure with a high-quality barometer, and don't trust your eyes too much. You can't judge whether the inflation pressure of the tire is correct from the appearance.

1, the standard air pressure can usually be found in the following places: the owner's manual, the label next to the cab door (near the B-pillar), the drawer next to the driver's seat of the vehicle, and the door of the fuel tank cover.

2. How much tire pressure should be hit, which is subject to the recommended value of the car factory. This is because the setting of tire pressure mainly considers vehicle factors such as body weight and chassis height. It is not necessarily related to what brand of tires are used.

If there are no special regulations in the garage, there is no need for special adjustment in winter or summer. Of course, it is recommended that you measure the tire pressure at room temperature.

The recommended tire pressure mentioned above refers to the cooling tire pressure. The definition is as follows: at least three hours after parking or the tires are not more than 2 kilometers. If the tire pressure can only be measured when the tire is hot, please subtract about 0.3 bar (=4psi) from the measured tire pressure to obtain the tire cooling inflation pressure.
