Package Includes 1 x Automatic Preset Tyre Deflator 4 x Replacement Tyre Valve Caps 4 x Replacement Valve Cores 1 x Valve Core Removal Tool Why Air Down Your Tyres? Reducing tyre pressure when driving off-road increases the tyre's contact area with the ground, which can improve traction and ride comfort on sand, gravel, corrugations and uneven terrain. Automatic deflators make the process easier by allowing a repeatable target pressure to be preset instead of manually checking the tyre pressure throughout the deflation process. Before Ordering This product is designed for standard Schrader-style automotive tyre valves. Always select a tyre pressure appropriate for your vehicle, tyre construction, load and driving conditions. Tyre pressure should be checked with a reliable tyre pressure gauge after deflation, particularly when setting the deflator for the first time.
