Tuff Terrain Automatic Tyre Deflators Brass (Set of 4)

Basically you screw onto the tyre valve. It will hiss until it stops at your preset psi pressure level (say 20 psi is a general beach driving pressure). Take the unit off your tyre and enjoy safe beach driving.

All 4 units can be put on continually then screwed off straight away. Or 2 can be set for 20psi and 2 for rougher 15psi conditions.

General Features:

• • Comes with small carry leather pouch.
  • Solid brass fittings that are rustproof and reliable.
  • Each unit has to be pre-calibrated by you ( from 6 to 30 psi) with easy to follow instructions.
  • 1 year warranty.
