finally got myself some Stauns thanks to my better half and my taking on years.... :)

Got the 6-30 psi model.

I'm planning to set each to a different pressure, from 10 or 12 up.

But before I fool around with the settings, I'm wondering, are these things accurate enough in practice around 10? 10 is pushing it for me, and if it ends at 5, say, instead, that's not great.

So, if you set them to 10, do they reliably and consistently deflate to 10?
 
they are pretty accurate I'd say within a psi +/-
 
They are sensitive to the ambient temperature, after they are made out of brass, and a PITA to set to lower pressures. Don't worry about messing up the factory settings, mine were all different until I tweaked them in.

I wish I had just gotten the Oasis type.
 
I love mine, I find they are really acurate (12 psi is about as low as I go) and easy to use, I spent about an hour dialing them all in, but now, just screwing them on and hear them hiss is a sweet feeling.

If you use an accurate tire gauge when you set them they work well.

Save yourself the time and hassle and use a bike tire to set them rather than airing up the vehicle tire each time until you find the correct psi.

Side note slightly off topic: if you air down in the AM at the trail head it's a good idea to check tire psi after wheeling because the psi will change once the tires get hot.
 
I'd agree they're pretty accurate. I set mine to 10 psi with a low pressure gauge and got them pretty close. After airing down all 4 at once, I've got 10.5, 10, and 9.5 readings. I'd say that's pretty good. :cheers:

They're nice, but I still like pulling the valve core out. Something about getting a bj I guess... :grinpimp:
 
OK, good to know, will give it a go then...
thx
 
I have had good luck with lower pressures as well down to about 6.5-7 PSI.
 
Where does a smart shopper source these?
 
OK, I did a repeatability test.

Used one of the Stauns that I had set to about 15psi. (I set them to 15, 20, 25, and 30. I normally run 40 on asphalt.)

Tested it on a small bike tire.

I did several deflates in a row, each time reinflating to approx the same pressure (45) with a comp.

I measured in order with a new (used 5x or so) Staun :

15.2 / 15.4 / 16.0 / 16.0 / 16.0 / 16.0

Reading error : about 0.2 psi.

Don't know what the small increase at first is about. Tire / valve / Staun getting warmer or looser?

Conclusion: at 15 they are repeatable enough that I think they can be used without worry of underpressure at that level. At 10 may or may not be the same... I'll stick with 15 for now anyway.


thanks all.


(Jon, Slee has them, and I'd recommend him highly. Note there are several models with different ranges.)

Right on,
thanks e9999 and rezarf.
 
Changing the pressure is not a pain!!!

Just make a mark on the body (of the Stauns)so you have a reference....It's THAT easy..

The instructions say that for every 1/4 turn it changes (I can't remember the exact #) like 3-4 psi... OF course of you're turning clockwise (increasing spring rate internally) you'll set it for a higher psi and vise-versa IF you go counter clockwise (less spring rate) It'll be a lower psi....

It's a hobby of mine. If you ever need to know how to turn $100 into $50 I'm your guy:D .
