How to deflate car tires?

If a pointer tire pressure gauge is used, when it is found that the tire pressure is too high, insert the gauge into the valve core to deflate, and measure the tire pressure at the same time. At this time, it is necessary to observe the numbers on the meter at all times to ensure that the normal tire pressure value is reached.

if there is no special tool, you can only use a valve core wrench or other fine-pointed objects to manually deflate the valve core. However, attention is needed, and the tire pressure of .2-.3bar can be released by slowly deflating for about 3 seconds. If the force is too large, the deflation is too strong or too long, it will cause too much deflation, resulting in too low tire pressure, which is also not acceptable.

Precautions for automobile tires

Before we are as familiar with choosing tires as we are with choosing daily necessities, it is a relatively reliable way to basically go to an automobile tire store. After all, tire stores are often directly established by tire manufacturers, which has a relatively good guarantee in terms of product quality and after-sales.

But it doesn't mean that the quality and service of some tires sold by non-specialty stores are not good. If the owner thinks that the tire specialty stores in his area don't believe it very much, he can also go to 4S stores or stores with good reputation to buy them.
