The rules of tyre inflation
When inflating, try to keep the pressure of each tire equal, and at least keep the pressure equal to the left and right tires;
The tire is marked with the largest cold tire pressure, unit kPa, 1bar=100kpa, at maximum allowable air pressure minus 0.3bar is normal driving pressure (cold tire inspection)
3, check the tire pressure should be separated from the cold tire, the source of gas measurement shall be accurate (that is, after the gas connector pulled out and then plug back to measure);4, after the completion of the gas, check whether the gas leak (use ordinary water can), so as not to gas mouth did not return, resulting in gas seepage.
