A really clever, new accessory from ARB is the tire pressure gauge with quick deflator function, which makes it easy to lower tire pressure for off-road use.

Here's how it works:

First, the brass attachment is placed on the valve, and then the valve core is unscrewed – so it can't get lost. The desired tire pressure is then set using a sliding valve. This is very precise, as the tire pressure can be read on the manometer. Afterwards, screw the valve core back in and "done!"
