How do you see the tire pressure when using a car tire inflator pump?

Correct use of tire pressure gauge:

1. The angle between the center line of the air pressure measurement port and the axis of the watch body is 90°-180°, the scale is a cuboid, and the range scale value is 0.07Wpa-0.4Wpa. Before reading, gently tap on the instrument casing or surface glass with your finger to eliminate friction in the transmission mechanism.

2. The pointer overlaps with the mirror pointer during observation. At this time, the index value of the pointer is the barometric pressure value, and the reading is accurate to one decimal place. Read the temperature indicated value on the barometer, accurate to one decimal place.

3. Align the measuring end notch of the air pressure gauge with the tire valve and compress it tightly. At this time, the pointer of the tire pressure gauge is deflected, and the indicated value is the inflation pressure of the tire, or the benchmark of the tire pressure gauge is pushed out by the air pressure, and the value displayed on the benchmark is the inflation pressure of the tire. The greater the pressure, the more biased the pointer.

Precautions:

Inner circle value: pounds per square inch;
Outer ring value: kgf/cm2 (engineering atmospheric pressure) = 1.033 standard atmospheric pressure = 1.02 bar.

If it is a car tire, it is generally 2.0~~2.5bar, not more than 3.5bar;

If it is a light truck tire, it is generally 6 levels, 3.0~~3.5bar;8 levels of 4.0~4.5bar;10 levels of no more than 5.5bar;

If it is a trailer tire, it generally does not exceed 4.2 bar.
