  1. Place the nozzle of the tire pressure gauge on the tire valve you wish to measure. Press firmly to ensure a good seal and prevent air from escaping.
  2. Hold the gauge on the valve until a seal has formed and the measurement has been taken. It should only take a second if you have a good seal.
  3. Remove the gauge from the valve stem.
  4. To remove air, use the deflation stem on the opposite side of the nozzle head.


  • Range: 0-75 PSI; 0-5.5 Bar; 0-550 kPa
  • 4-sided ABS Indicator Bar


In order to get a strong seal, place the nozzle directly onto the tire valve. Putting the gauge on the nozzle from an angle could result in an inaccurate reading. Once the gauge is placed, firmly press the gauge straight down.
