The TireBuddyIII is a deflator, one that screws directly onto a valve stem (after removing plastic
cover) just like a valve cap. Once threaded into place, it automatically deflates the tire to a specific pressure (adjustable from 10 pounds per square inch to 30 psi) and emits a whistling sound that gradually diminishes as the air pressure decreases.
Each TireBuddy III comes pre-set to 15 psi, generally considered the ideal air pressure for beach travel and owners of 4 wheel drives.

We also carry the very popular Oasis Trailhead Automatic Tire Deflators!-
