ROADGEAR Programmable Hi-tec Digital Tire Gauge
You can program it to show the recommended front and rear tire pressures. A quick press on the tire stem displays the pressure on a bright blue background. The 90 degree tip is rotatable allowing for right or left handed operation and will fit in the tightest spots-easily clearing large disc brake rotors. Even a handy light is built-in for nighttime valve stem illumination.
