What about Tire Pressure Gauge?

The tire pressure is equivalent to the life of the tire. If it is too high or too low, the life of the tire will be shortened, or the tire will burst. For our car owners, the car tire pressure gauge can be said to be a frequently used tool, and the car tire pressure gauge is also the most intuitive way to detect the car tire pressure. However, many friends did not know how to view the tire pressure gauge when using it for the first time. This is normal, and we will conduct a detailed novice teaching below.

Tire Pressure Gauge is generally divided into three types: pointer tire pressure gauge, digital tire pressure gauge and alarm tire pressure gauge. The latter two types can tell us the tire pressure through numerical values or alarms. The principles are relatively simple, and The most common type we use every day is the pointer tire pressure gauge. As long as it is connected to the tire valve, we can check the tire pressure of the car, and then look at the pointer of the meter head to understand the tire pressure. Although the pointer tire pressure gauge is also simple, But unfamiliar friends are prone to misunderstanding, so let's take a look at the pointer tire pressure gauge first.

Tire Pressure Gauge

First open the valve cap of the tire, connect the valve of the tire pressure gauge to the valve of the tire, and hold it until the pointer reaches the highest value and start to release the tire pressure. After measuring the value, remember to cover the valve cap.

You can see that the tire pressure gauge has two turns, one is the English unit of psi (pounds per square inch), and the other is the unit of kg / cm 2 (kg / cm2), and we usually say 2.5 means inside Circle the black number, as shown in the figure we have marked the exact position of 2.5 with a logo. If the tire pressure is too low or too high, you must set the tire pressure to a proper and correct position. If you don’t know, you can consult the vehicle user manual or the sign next to the door (B-pillar or C-pillar attachment), where you can see the manufacturer's recommendation Value (cooled tire pressure).

The second type is a digital tire pressure gauge. The digital tire pressure gauge works the same as the pointer tire pressure gauge, but the digital tire pressure gauge uses an LED digital display, which means that the digital tire pressure gauge is more accurate than the pointer type in reading accuracy The tire pressure gauge has been improved a lot.

The third type is the alert tire pressure gauge. The alarm-type tire pressure gauge does not display the tire pressure value. If the alarm-type tire pressure gauge finds that the tire pressure is abnormal, it will issue an alarm.

It is worth mentioning that the tire pressure check must be performed when the tire is cooled, otherwise the high temperature will increase the tire pressure. If the air pressure measured in the case of a hot tire, it is best to subtract about 0.2 to be the tire Cold inflation pressure.
