Why does the tire look flat, but the tire pressure is normal?

Tires are vital components. Under normal circumstances, if you travel far away, the owner will definitely check the tire pressure of your car to see if your car is still "angry". Then the problem is coming. Some car owners may have found that their cars have obviously increased their tire pressure. Why do tires deflate after a long time? There may be many drivers who don't understand. Let's see why:

First of all, some vehicles will have their own tire pressure monitoring devices. Insufficient tire pressure will automatically alarm, and the owner does not have to worry about the problem of insufficient tire pressure. In addition, if there is no tire pressure monitoring device, the car mainly develops the good habit of checking the tires before getting on the bus. See if the tires are flat or if the car body is a little tilted. At this time, the front wheel is deflated unilaterally. When accelerating, the owner feels that he can't lift the speed, or it may be the problem of tire pressure.

Secondly, when driving, I feel that one side of the car will be slightly lower than the other three sides, and at the same time I feel that the tire noise will become louder. At this time, there must be insufficient tire pressure on one side. It is recommended to stop and test. Tell everyone how to judge the front wheel: when the tire pressure on one side of the front wheel is insufficient, releasing the steering wheel will slightly deviate. Every tire has teeth, and we can judge whether the tire pressure is normal by looking at the number of times the teeth contact the ground. Generally, if 4~5 teeth touch the ground, the tire pressure is just right at this time. Less than 4 indicates high tire pressure; If it is greater than 5, the tire pressure is low. At this time, it is necessary to pump up the tires in time.

Many people think that the tires of a car are the same as the wheels of a motorcycle. If they are flat, they will look a little different. In fact, most cars now use vacuum tires, which means that there is a layer of "gas" inside and outside the tires. It looks flat, but it is not flat. The tire pressure range is mostly between 2.2 and 2.6 bar. As long as this standard is reached when inflating, the tire will be adjusted according to its own pressure! So if you still feel flat after filling up, don't worry about this situation at all!
