Trailhead Automatic High-Range Tire Deflator

This High-Range Trailhead Tire Deflator is an essential item for those who like to drive on dirt trails, mud and sand. This deflator will "air down" the tire quickly for increased traction on unstable or slippery road conditions. The mount-to-valve stems makes this deflator easy to use. The automatic tire deflator features a turn adjustment screw that you can turn clockwise to increase the PSI or counterclockwise to decrease it. One full turn will change the tire's pressure by 1.5 PSI. Once the desired change is reached, the deflator shuts off.
