The valve of a tire is an independent valve body device. When the valve is opened, gas is allowed to enter the space of a tubeless tire or inner tube, and then the gas is automatically closed and sealed to generate air pressure to prevent gas from escaping from the tire or inner tube.
Except for solid tires, other tires or inner tubes that must be inflated need to be inflated with this device.

1, pay attention to safety when inflating. Check the air pressure with a barometer at any time to avoid puncture due to over-inflation.
2. After stopping driving, be sure to wait for the tire to dissipate heat before inflating, because the tire temperature will rise when the vehicle is driving, which will have an impact on the air pressure.
3. Check the valve.
4. Pay attention to cleaning when inflating. The filled air must not contain water and oil to prevent the inner tube rubber from deterioration and damage.
5. When inflating, don't deflate after exceeding the standard, and don't inflate too much because you can't inflate for a long time. If it exceeds the standard, the cord will be stretched excessively, which will reduce its strength and affect the life of the tire.
6 Before inflation, the dust on the valve should be wiped clean, and the valve core should not be loose. After inflation, apply soapy water (or saliva) to the valve to check whether there is air leakage (if air leakage will produce small bubbles). The valve cap should be assembled completely and tightly to prevent sediment from entering the valve.
7. When radial tire is inflated, due to structural reasons, its sinking and grounding area is large, which is often mistaken for under-inflation and over-inflation; On the other hand, because of its large subsidence and grounding area, it is mistaken for sufficient when the air pressure is insufficient. Measure with a standard barometer. The service pressure of radial tire should be 0.5- 1.5 kg/cm2 higher than that of ordinary tire.
8. Check the vehicle-mounted barometer or barometer used in the tire workshop regularly to ensure the accuracy of the air pressure check.
