Dial-type tire pressure gauges are popular with professional mechanics because they are very accurate and easy to read. The CruzTOOLS® TirePro™ gauge has a 12" flexible hose that makes even hard-to-get-to valves less of a task. Readings are held until released, and a built-in valve lets you bleed pressure to the desired level. Readings are in psi and kPa, and the dial is protected by a rubber boot.
