Maintain normal tire preure; 2. Improve vehicle driving safetyProduct advantages:1. Connect the air compreor to directly inflate the tire2. Can directly measure preure3. Use special explosion-proof tubeHow to use:1. Unscrew the cap of the tire valve;2. Buckle the preure measuring nozzle head of the inflation gun and pre it on the valve;3. The tire preure gauge will display the tire preure. If the tire preure is insufficient, proceed to the next step and deflate back to zero;4.
