I did a search, but didn't see what i'm looking for...

Has anyone heard of little cap-type things that you screw onto your tire stem valves, and they let the pressure down to a predetermined amount? Like if you buy a set of them at 15 psi, they let the air out until your tire is at 15 psi.
Has anyone heard/seen these before, if so can u post a link please?

http://www.oasis-off-road.com/page2.html is what I use, you canadjust them for the pressure you want...

I have seen them called "air downs" Pretty expensive. The prices I saw were around $40.00. I think JC whitney has them.

Pretty cool, but no way I'm paying $40 for sheeot like that!

I think Launch had the right response, Fawk that, for $40m bucks I'll stand there and put the $40 toward something else. :D

Just pull the core out and wait until they start whistlin

Thanks for the link Crazyhorse.
It is a bit much though, i'll look around more...

I just take out the stems, wait five minutes, put stems back in and air up to 5-8 psi with my parts bin special powertank. Quick and simple, not to mention I didn't spen $40 American on fancy valve stems.
