The weather is getting cold and the tire pressure of the car is too low. Do you want to deal with it?

Deal with it. Because the tire is inflated, and the gas is greatly affected by temperature, under normal circumstances, the gas will expand when the temperature rises and contract when the temperature decreases. Therefore, the gas filled in the tire is greatly influenced by the external temperature.

Generally speaking, the change of outside temperature from 8 degrees to 10 degrees will have an impact on tire pressure of 0. 1bar. That is to say, if the temperature rises by 8 to 10 degrees, the tire pressure will probably rise by 0. 1 bar. If the temperature drops, for example, from 345 degrees to 17 degrees, the tire pressure may drop by 0.2 to 0.3 bar.

If the nominal tire pressure of the car was 2.3 at that time, you will find that the driving tire pressure will reach 2.0bar at this time. Even if some cars linger on the edge of 2.3bar, they will drop to 1.9bar. Many cars will start to report to the police when the tire pressure is monitored to 1.9bar. At this time, it is found that the tire pressure is insufficient.

Extended data:

Therefore, in such a car environment, if you cling to the tire pressure, it is also very tired. So if it is a city like Changsha, the temperature is repeated at this stage. As long as your tire pressure doesn't keep running at low temperature, you can leave it alone without refueling.

Of course, it doesn't matter if the car is equipped with an air pump. You can inflate the tires at any time. It's convenient anyway. If not, you have to find a place to repair the car and find a place to maintain and inflate the tires. It's too much trouble and unnecessary.
