How to read the tire pressure table of a car?

1 use the tire pressure gauge correctly. The included angle between the center line of the air pressure measuring port of the tire pressure gauge and the axis of the meter body is 90-180, the scale is quadrilateral, and the range scale value is 0.07Wpa-0.4Wpa Before reading, tap the instrument shell or surface glass with your fingers to eliminate the friction in the transmission mechanism. 2 When observing, the pointer overlaps with the mirror pointer when observing. At this time, the indicated value of the pointer is the air pressure value, and the reading is accurate to one decimal place. Read the temperature value on the barometer to one decimal place. Align the notch at the measuring end of the barometer with the tire valve and press the valve. At this time, the pointer of the tire barometer deflects, and its indicated value is the inflation pressure of the tire, or the reference of the tire barometer is pushed out under the action of air pressure. At this time, the value displayed on the benchmark is the inflation pressure of the tire. The greater the tire pressure, the more the pointer deflects.
