What should be paid attention to when inflating car tires

1. Pay attention to inflation. Always check the air pressure with a barometer to prevent the tire from bursting due to excessive inflation.
2. Wipe off the dust on the valve mouth before inflation, do not loosen the valve core, apply soapy water to the valve mouth after inflation, check for air leakage (if the air leakage will produce small bubbles), and will The valve cap is fitted tightly to prevent sediment from entering the valve.
3. Check the valve. If the valve nozzle and the valve core are not well-matched, there are protrusions and recesses and other defects, it is inconvenient to inflate and measure the air pressure.
4. After stopping driving, wait for the tires to dissipate before inflating, because the tire temperature will increase when the vehicle is running, which will affect the air pressure.
5. When inflating, do not exceed the standard pressure too much and then deflate, or do not inflate too much because you can't inflate for a long time. If it exceeds the standard, it will cause the cord to stretch too much, causing its strength to decrease and affect the life of the tire.
6. Pay attention to cleaning. The air filled must not contain moisture and oil to prevent the deterioration of the inner tube rubber.
7. When the radial tire is inflated, due to structural reasons, its sinking amount and grounding area are large, and it is often mistaken for insufficient inflation and excessive inflation; or vice versa, because its sinking amount and grounding area are originally large, in When the air pressure is insufficient, it is also mistaken for sufficient. To be measured with a standard barometer. The operating pressure of radial tires is 0.5 to 1.5 kg/2 cm higher than that of general tires.
8. The air pressure gauge in the vehicle or the air pressure gauge used in the tire workshop should be regularly calibrated to ensure the accuracy of the air pressure check.
