I saw some of these fancy air-down valve stems a while ago in some magazine.

The ones I am looking for, you could buy different settings for the different air pressures you were looking for. They would screw onto the valve stem and only let out the air until it meets the designed air pressure, i.e. 20psi unit will air down to 20psi and stop letting air out.

Please help, I am going to the Outer Banks, NC in 2 weeks and want to get these prior to the trip.

Thanks in advance for the help.

since when is 20psi airing down?


They're made by trailhead and they're about $40 a set.

What is suggested for a set of 38" swamper Radials on 16.5 wheels beneath a Suburban?

Do you know if they have a web site, or suggest a place to get them?

Thanks

your pushing your luck if you air down 16.5 rims at all let alone under a heavy arsed burb i'd say 20 PSI is enough

.

Sorry found them Oasis Off Road (http://www.oasisoffroad.com/tireInflatorDeflator.html)

Anyone know the desired air-down psi for a set of 38" Super Swamper Radials on 16.5 wheels under a Suburban?

As low as you can with out costantly losing a bead...with a burban and 16.5" rims it's not gonna much less than 20 psi. Just start there and let a little bit more out everyonce and a while until it stops helping or you start losing beads easily.

I`ve found the air down adapters to be a joke.

$2 valve stem core remover and I can air down faster than someone with 4 of the gadgets made to air down.

Just be sure to carry extra cores incase one goes flying away if you don't pull itout slowly...

I agree with ya, I just use a valve core puller, and can get all four done in a hurry. :D

I run the Klune-V RAD valves.. they don't hit a certain PSI, but they'll flatten my 36x12.50 TSLs pretty quick - quicker, I think, than pulling the valve cores did.

It's also a lot easier to just crack the RAD a little to drop more pressure, while it's difficult to pull the core out to drop just one pound..

'course, my rear tires self-regulate to about 10psi between trail rides anyhow.. I have to air-up the day before a run.. :D

There was this old bull and this young bull on a hill top overlooking a pasture full of cows.........

I use the Oasis ones, as I'm in no hurry. Mine are set at 11 PSI. I just screw them on the valve stems, and go do other things, like disconnect my sway bar, or just B.S.. When they reach 11 PSI, they shut off. No rush, no fuss.

Bwhahaha... BTDT... At a gas station, at night none-the-less....

I'm a toole!!!

I use the Oasis airdowns kinda like frankenfab does.....I screw them in and do other things.....sometimes I just wonder down the line of rigs and pet the dogs.
When I'm alone and in a small rush, I screw them in and take off....let them air down as I go down the trail. Then take them off at a convenient stop.
I use the velve core removal tool 95% of the time....but the Oasis is handy when I want them. They go for about 45~50 bucks for the pouchful.
I have heard reports that they don't air down evenly and they get stuck....I never had it happen.

I use these:

They are not the pre-set kind, you've got to monitor it and stop it yourself.... But they run really fast compared to the Oasis kind. They go fast enough that I generally only do 2 at a time...

I find they fit my needs because I change my tire pressure alot based upon the terrain I'm on.

One of the guys in our club has the Oasis, and love them, but said he has had problems getting them to start is he has less than 35psi to begin with. Is this just an isolated issue?

no my brother has the same issue, 36" swampers on the back of a empty toyota don't need much pressure so he used to have alot of issues. Now he runs a spool and alot of pressure to help turning and has no issues getting them to work. I plan on getting the Klune-V ones, very slick setup

I agree. Haven't lost a core in 3+ years.

Carry a valve stem remover, and should also be carrying extra valve stems. Much cheaper, and just pull the stems until the tires start making a different noise.

I've had the Oasis for a few years now, but never use them- pulling the core is faster, much faster. Oasis pouch carrier my core pullers, tire gage, and four shiny red wastes of space.
The Oasis worked fine the first season I had them, but I think it may be rebuild time. They don't work worth a darn now, a couple won't let air out at any setting. I think maybe the moisture from the air is gumming them up inside.

Thanks everyone for the suggestions, I think I may purchase a set of the Oasis' (http://www.samsoffroad.com/samsoffroadsto/SunEquipmentDeflators.htm), and a set of the Quick Air Deflators (http://www.samsoffroad.com/samsoffroadsto/SunEquipmentDeflators.htm)

I will only really use them for one week a year when we go to the Ocean so I should be OK?

I read in Peterson's 4Wheel & Offroad a segment on fitting a set of 42's with 16.5" wheels attached to a Dodge, they said 17psi was the limit for those tires and wheels. Would that be the same for the 38's on the 16.5 wheels?

I like the Staun Tire Deflators, they are almost dead on from what I have seen.

I wonder how you set the pressure?

I have a set of these too, I can air down all 4 of my tires with the core remover and these will only be half done, they don't let all the air out as fast as the core remover and also some air down at different rates.... Screw all 4 on around the vehicle, and #2 may have tons mroe air than the last one (#4) so it gets confusing having to check them all..

Core remover remove 1 at a time and be done :D It's cheapest too!

The Stauns look pretty cool. The white button on the end allows you to push it and let bits of air out at a time. The thin, wide-diameter dial is how you adjust the air setting. A buddy of mine just bought a set; I pulled the core and aired down two tires beforfe he got one calibrated, so jury is still out of them. Like I said before, my Oasis worked like a champ the first season- then all downhill from there.

I use these, have for about 2 years. Yeah, they're not as fast as core removal, but you can do all 4 at once, still only takes a few minutes, I find them easy to keep track of, and they have no moving parts, I've never had them clog or anything. And, hell, they're $10, you're not breaking the bank here. You can put the gauge right on them, and I can easily put all 4 tires to 10psi +-1 psi without any thought or effort. Also, you can loan them out and do 2 or 3 rigs at once, not a good idea with core pullers...

These are great and only cost around $10.00. Just screw them on to each wheel, when the first tire reaches the desired pressure, simple remove the others in the same order you installed them. Takes me less that 10 min. on 36" TSL's down to 6 psi;)
