Check out the tool box of your local mechanic, or in the race pits, and you're likely to see dial-type tire gauges because they're very accurate and easy to read. The TirePro gauge has a 12" flexible hose that makes even hard-to-get-to valves an easy endeavor, and a built-in valve lets you "bleed" down to the desired pressure. Readings are in psi and Kpa (up to 60 psi), and the dial is protected by a rubber boot.
