How long does it take to inflate a car tire?

Generally, it is inflated once a month or two.

Tire pressure will change with the external environment such as temperature, humidity and altitude, especially in winter and summer. The air pressure changes in the north and south are different, so it is impossible to have an accurate inflation period.

Secondly, the quality of the tire also determines the frequency of checking the tire pressure. A good set of tires only needs to be checked when the season is changed, and the temperature is raised and lowered. There is no hard and fast rule about how often it expands under normal circumstances. However, for family cars that are used normally every day, it is good to check the tire pressure once every 3-4 months, which is basically a minor change. Just inflate it with a little air pressure according to the actual situation!

It is a simple and complicated problem to judge whether the air pressure is short of air. Generally, an old driver can judge whether the tire pressure is normal by looking at it with the naked eye or even kicking it with his foot, but this is not absolute. Unless you have enough experience or the tire is obviously leaking, you can simply identify the abnormality. There is a very simple trick, that is, park your car on a flat road, and each tire has a pattern to see if it is affected.

Extended data:

For many car owners, they don't always pay attention to the tire pressure. They often go to the car wash shop to refuel when they see a flat tire. But at this time, the tire may have been in a state of serious deflation, and the tire wall could not be properly supported. Not only will the fuel consumption increase, but the inclination will also increase when turning, and the probability of overheating and puncture of tires at high speed will be greater. On the contrary, if the tire pressure is too high, the contact area of the tread will be reduced and the braking distance will be greatly increased, which will also affect the grip of the tire when cornering. Abnormal tire pressure driving for a long time will also cause serious abnormal tire wear, greatly reducing the life of tires.

It is recommended that every car owner keep an electric air pump and a tire barometer in the car at all times. After all, the barometers in many car beauty shops have been in disrepair for a long time, and the errors are often very large. To be on the safe side, we should bring a high-quality portable tire barometer. Under normal circumstances, we only need to check the tire pressure once a week when there is no obvious abnormality in the tire wall. Generally speaking, tires are inflated every 1-2 months.
