5) manually tire is charged and discharged gas: the joint at band valve inside screw thread place connecting band valve inside thimble can fill, exit the tire that valve connects by charging and discharging the gas special tool;
6) measuring wheel tire pressure, but connect just measuring wheel tire pressure of pressure measurement instrument table at band valve inside screw thread place.
