A digital tire gauge with a tread depth indicator.
The Accutire Pen Style Gauge is a precision electronic instrument that will give you accurate tire pressure and keep a check on worn tread depth.
To measure pressure accurately: Align the nozzle of the tire gauge with the valve stem on your tire. Apply suffiecient force to engage the nozzle with the stem, while maintaining a proper pressure seal. As you engage the tire gauge to the valve stem, a sudden surge of air will create a crisp sound. Listen for any leaks, and press firmly on the valve stem to obtain a good seal.
When pressure is applied to the unit, the display with first flash an all segments test, then display the actual pressure. Hold the tire gauge on the valve stem until a reading appears on the display and locks. After reading has locked on the display, remove the tire gauge from the valve stem. The display will remain illuminated with the pressure reading for 10 seconds.
To measure tread depth: First, set the slider to zero. Then, hold the gauge flat against the tread to be measured and push the slider until it meets resistance. Remove the gauge and read the tread depth indicated by the slider.
