Staun Tire Deflators By Jason West

The latest cool offroad product to come out of the Land Downunder is Staun's Tyre Deflators. These nifty gadgets air down your tires to a pressure you preset, then automatically shut off, very similar to the Oasis Trailhead Deflators I reviewed back in March of 2001.

Like the Oasis deflators, the Staun deflators come four in a set and include a leather storage pouch, though the Staun pouch is almost too small to stuff the four brass deflators into. On the back of the bright orange package is a small instruction card that you can cut out and store in the pouch.

Setting them is pretty easy. You'll need to air down one of your tires (I used my spare) to the pressure you want, then screw a deflator onto the valve stem. Loosen the knurled lock ring and turn the outer cap counter-clockwise until air starts to escape, then screw the cap back down to just when the air shuts off. Now tighten the lock ring against the cap and repeat the process for the remaining three deflators.

You'll loose a bit of air each time you set a deflator, so check the pressure between setting deflators and added some pressure if necessary. This process paid off for me because checking the pressure settings of each deflator after it was all done showed them to be within 1psi of each other. Not bad...

The Stauns are fully adjustable from 6 to 30psi, and come preset to 18psi. I set ours to 13psi. It took exactly 4 minutes to air down my 35x12.5R15 Goodyear MT/R spare tire from a street pressure of 28psi to a trail pressure of 13psi. That's not quite as quick as the Sun Performance Quickair key chain deflators, but it's a trade-off I'm more than willing to make to not have to mess with constantly checking air pressure as the tires are airing down.

The Staun Tyre Deflators are available from a number of dealers, I picked up my from my friend Mike Cohn over at 4x4rockshop.com. At the time of this article they're selling for about $50 through the RockShop.
