In winter, how much is the automobile air pressure normal?

in winter, the automobile air pressure is generally around 25kpa, which is considered normal.

Generally, the tire pressure of automobile tires is about 23kpa to 25kpa. However, when the temperature decreases in winter, the tire pressure will also decrease due to the influence of the external temperature, so it should be raised. If the tire pressure is too low, it is easy to have a puncture, which will have a great impact on the driving of the vehicle.

Now many vehicles are equipped with tire pressure monitoring system, and the current tire pressure can also be seen on the dashboard or central control panel, and the system will give a reminder if the tire pressure is abnormal. If these are not available, a tire pressure gauge can be equipped to measure the tire pressure of the wheels before driving the vehicle every time.

Check the vehicle

This is because the gas in the wheel will expand with heat and contract with cold, so when the temperature is low, the tire pressure will be lower than usual. When the tire pressure becomes low in winter, some car owners may think that it will recover when the vehicle is driven, but before the tire heats up, driving the vehicle will already cause wear and tear to the tire.

after buying a car, the manufacturer will usually give us a vehicle manual, in which the appropriate tire pressure will be explained, and our owner can adjust the tire pressure according to the above suggestions. If the manual has been lost, you can also see how appropriate the tire pressure is on the car fuel tank cover and the frame next to the cab.
