Trouble airing back up? TPMS info inside!

[JAYB1RD]

On my first trip offroad with the H3 I had a problem bringing the tires back up to the proper pressure for the drive home. It's because the TPMS valve stem is so short, that the average gas station that has the angled air chuck can't fully seat onto the valve. So there I was, stuck in the middle of Michigan with only 20psi in my tires and no way to pump them back up! Fortunately for me, the gas station down the road amazingly had one of the straight air chucks, and I was able to fill the tires. Once I got home though, I put a couple valve stem extensions in my grab bag of parts that rides in the back of the H3 on trips like that. My friend who was with me at the time has since come up with an even better solution.

Longer valve stems is his idea. GM p/n 15136883 or 15114379 will work with the H3s TPMS system, but the stem is about 1/4" longer so the angled air chuck can be used. Each of those numbers is the same part, but his system has two different prices listed for them. So get a quote on both before you buy. GMpartsdirect.com has them both listed at $30.50, which is where I will order mine from soon.

p/n 15122618 is the stock valve, just FYI.

Enjoy! Feel free to ask any questions.

You should carry your own compressor as a back up:twak: ;)

I also carry a extra air hose,at the beach they only supply 2 air hoses.On a busy day there is a line ,they provide apx 8 more air supply locations to hook your own hose to.The one I have has a lock to keep it on the valve and also a built in gauge.
Think about installing a compressor under the hood.The masterflow will air up from 18psi to 35 psi under 2 minutes a tire.
Easy install :D use search for install pics and info.
better safe then sorry

be careful a longer stem can get taken out by a rock or branch or whatever you are running over and around , easier than the shorties ;)

:iagree: You should invest in a compressor or CO2 setup instead. Or at least make sure that whoever you're wheeling with has one.

Awesome set up 442! I like the compressor set up myself. Save the hassle of filling up a CO2 tank every other time you wheel. Although having the ability to reset a bead is nice with the tank set up. On my old heep I had a custom front bumper that held the compressed air from the compressor and a air port on the front for easy fill up. that gave me the extra capacity to run air tools, and whatever else. Kinda cool idea until it gets pierced by a rock. boom! Definately a plus to be self sufficient and not have to worry about finding a gas station. :beerchug:

442: could you possibly link me to where you picked up your compressor?

[JAYB1RD]

I thought about on-board air, but decided this was better for me and thought I'd share what I found with anyone else looking for an easy solution.

All the places I've ever wheeled have had free or cheap air close by, and that's counting the middle of the Michigan UP. It'd be nice to have on-board air, that's for sure. But I just can't justify it, especially mounting a compressor into a leased vehicle. And I can't sacrifice the room for a large air tank either I don't think. Half of my cargo area is already full with tools and recovery equipment. I need to have room for camping gear and a cooler too on trips.

The longer valve stems are only 1/4" longer, just enough to fit the angled chuck without bottoming out against the rim. They won't be any more prone to being damaged than the stockers, especially considering the angle they come out of the rim at. At worst, they'll be 1/8" closer to the offensive object. I think this will work out the best for me. Thanks for lookin out though!

You can get one at Pep boys or on ebay

Thanks brudda! :beerchug: What are the effects if any of mud on the compressor? Is everything sealed pretty good?

Edit: Shower caps, got it! :perfect10s:

[usetosellhummer]

I got a small one that fits in the rear cubby area for 79 buks at recovery.com or something, I have to use it eveytime. almost no gas stations offer or have functioning air compressors in this area. Look for one that posts inflaction times I can air up all for from 20 to 30 in aobut 12-15 minutes.

I'd like portable compressor (or hose extension) with a low profile chuck.

Those rims look pretty sweet. Can you post a full pic? Haven't seen them mounted on a rig yet? :beerchug:

I agree, the valve stem may seem to be short, but it has never stopped anyone I know with an H3 from airing back up. This is with 90 degree chucks too. In fact, that is all I have. You have to find the correct position to place it, and push hard, but it can be done.

They are Cepek wheels by R.T. Cepek's company GT Inc. (http://www.hummerproducts.com/)

http://flashoffroad.com/catalog/original/wheels/H3/H3wheels.htm

http://www.detnews.com/2005/autosconsumer/0509/14/F03-313860.htm

They are basically powder coated H3 wheels with matching trim rings. The rings, while having loads of stainless steel bolts, are held on to the wheel by six of the bolts. The others are for show. The wheels and rings can be done in multi-colors (wheel, ring, and cap). You can get 'em to match the color of your ride. Mine, however, is all black...or almost. If you get some -- tell R.T. some mountain biking Army guy sent ya.

Now, if JAYB1RD and I could find a compressor (or hose) with a low profile chuck. :popcorn:

[RubHer Yellow Ducky]

I have that compressor but have a question...

What do you think the long term effect will be on the compressor from the heat generated under the hood?
