yeah me 2; same as Beatit.
One set at 15 psi for beach runs - these are dobbed with yellow acrylic paint by me over the lock ring. The others at 28 psi - they are with a white dob of over the lock ring so I can see if the adjustment has accidentally altered.
Here is a copy of an article I wrote for the 4Wheeling SA on-line magazine. I have left the pictures out.

There’s lots of gimmicky things that tempt a four wheel driver to part with his cash.
But here’s one that may just be worth investigating – Staun Tyre Deflators. As the ad says, they will let you down. And for setting tyre pressures at a predetermined level, they work
well. By adjusting a brass ring, and screwing the deflator onto the valve stem, they are the easy way to drop tyre pressures to increase traction.
Let’s imagine I’m at
Robe and about to cruise through the
Little Dip Conservation Park. I’ve got 3 mates on board, a few coldies, some fishing gear, and the cricket is on the radio. Having come off the blacktop, my tyres are at 36 psi.
In the past, my mates & I used to let tyres down the old way. With one person on each tyre, I would count slowly to 45 (out loud) & we would all in turn
check the pressure, which experience told me would be close-ish to what I wanted. Then it was fiddle-faddle with the tyre gauge to get all four tyres to exactly what we desired – all up at least 15 minutes.
However, by screwing on the 4 Stuan valves, the tyres now emit a persistent hiss of air to settle at exactly 18psi. By the time I have screwed the last of the four valves on, the first tyre is deflated exactly to my preset pressure. It’s over, and it took less than five minutes.
So what I’ve saved is a heap of fuss and time. No more mucking about with small sticks/keys/screwdrivers to press the valve in to let air escape. No more do I need to
check each tyre 4 or more times to get it exactly to that magic psi level. The Staun’s get you there in one motion.
It might be fun the first couple of times all jumping out to let the tyres down, but the novelty soon wears off. Remember, there are more important things to do – like opening beer! If you’re driving in different conditions, maybe it’s worth getting two sets of Staun’s with one set calibrated at 28 psi for dirt roads, and another at 15psi for sand.
Cheers
