Valve Stem Mod

[Yvonnemarc]

So I had some trouble getting the air pump nozzle to fit into the hole in the front wheel hubcap. Trying to clamp it onto the valve stem...its a PITA. Have to over inflate the tire 2-3 lbs cuz then you have to unclamp the nozzle and wrestle it off all while losing air...ARGH!!!
But I discovered this for about $10. Problem solved.Attachment 10613

Yep; I did that a year ago with my ACE.

I live in a town that only has one RV repair place and one rv parts store and they wouldn't have those extenders. With that problem I looked it over and got a big set of pliers and bent the hubcap valve slot to make it wider. Seems like every time I used to park it the valve was impossible to get to, but now... it's easier. Need to get a TPMS now.

Do you ever worry about the outward force generated by the "cetrifugal" force constantly pulling on the valve stem due to the additional weight of the extender and the wheel rotation? Maybe sometime when you are going down the road the valve stem might just pop out. I prefer to just purchase an air fitting that fits through the hubcap.

Nope, and I have TPMS sensors on mine as well.

Nope, they don't weigh that much and the wheels don't turn fast enough for that to be an issue. (I also have TPMS sensors on the end of the valve stems.)

A little calculation: 225-75R16 tire's diameter is 29.5", circumference is 92.6" which means the wheel is rotating at 5280*12/92.6 times per mile (684). At 70 mph we're talking 1.16 miles per minute or 798 rpm for the wheel. Not that fast. (LOL or 684 rpm for 60 mph..)

FYI this is what I put on the rear wheels of my Vegas. So far so good. It "says" it's only for big rigs, but if you're even slightly handy you should be able to figure out how to mount it on most any wheel or wheel cover.

(Don't pay attention to the reviews, the reviews on the exact same product but different pressure models have perfectly fine reviews. It's an impressive looking piece of hardware and should work fine.)

I added those extensions too, but I do worry that they could start to leak. Has anyone run into that problem? I also have my TPMS sensor attached.

I used to use the valve extension until one day I noticed that one of my front tires was flat. The extension came loose and lost all the air. (at least it was between trips). I took the extensions off and now use this to add any air in the front tires: https://smile.amazon.com/gp/product/...?ie=UTF8&psc=1.
It makes it a lot easier to put air in the tire.

Since the valve stems are actually pulled through from inside the rim (large rubber stop that’s part of the valve stem to prevent it from pulling all the way through). There’s no way it would pop out.
I just added a short extension that’s virtually no weight so I’m not worried.

May be OK to add/check air but no good for installing a TPMS sensor.

No, you can't have the TPMS on it, it would just flap around like a fish on a hook. I use it to put air in the tire, then take it off and then put my TPMS back on the stock valve stem.

Can't do that with the wheel covers on many of the Thor coaches. The stock valve stem is too short and/or at the wrong angle.
