The Dunn & Watson 4WD Digital Air Down Tool gives you a simple way to deflate tyres while keeping a clear eye on pressure. It is ideal for drivers who regularly lower tyre pressures for sand, gravel roads, corrugations, rocky tracks or remote touring conditions.
This digital tyre deflator uses a valve core removal style setup to help air escape faster than standard press-and-check deflation methods. While the tyre is airing down, the slide valve allows you to quickly check the current pressure on the digital display, then continue deflating until your target pressure is reached.
The LED backlit screen helps improve visibility in low-light conditions and supports multiple pressure units including PSI, BAR, KPA and KG/CM². This makes it easy to use across different vehicles, tyre setups and personal preferences.
The kit is built with practical off-road use in mind, including a braided steel hose, brass fittings, secure crimps and a protective rubber bump guard around the gauge. Compact enough to keep in a glovebox, recovery bag, canopy drawer or touring setup, it is a reliable tyre pressure tool for regular 4WD use.
