How To Maintain Car Tires

1.before inflation should be on the valve dust wipe, do not loose the valve core, after inflation finished with soapy water (or saliva) painted on the valve mouth, check whether leakage (if leakage will produce small bubbles) , and valve cap with tight assembly, to prevent sediment from entering the valve. 

2. When the radial tire is inflated, due to its structure, its sinking amount and grounding area are both larger, which is often mistaken as insufficient inflation, and it is inflated excessively; or conversely, because its sinking amount and grounding area are already larger, when the air pressure is insufficient, it is also mistaken for sufficient. Measure with a standard barometer. The air pressure of the Radial tire should be 0.5-1.5 kg / CM2 higher than that of normal tyres. 

3.The on-board pressure gauge or the pressure gauge used in the workshop should be proofread regularly to ensure the accuracy of the pressure check.
