I've had repeated problems with the passenger side rear wheel valve stem extenders working loose on trips resulting in slow air leaks to the inside rear tire. I tighten the extender and the air leak stops for a while. It seems to work loose every 3000-5000 miles. I love the convenience of the extenders, but concerned about repeated problem. No problem with drivers side....I even switched the driver side and passenger side extenders and still had the same problem. Anyone have same issue? Saw the earlier posting on loose valve cores. This is the extender that works loose and causes an air leak. Any simple suggestions for securing the extender without causing other problems?

Have you tried putting a drop of blue loctite on the extender? I don't know if it will work but it might.

What is it about the right side?
The right inner extender on our Pace Arrow worked loose and the tire went flat.
The right inner extender on our Alpine worked loose and the tire went flat.
The right inner extenders on all 3 of our Phoenix Cruisers worked loose and the tires went flat.
Peculiar, to say the least.

Our 2007 PC2350 with 17,000 miles, the tire hoses are holding up perfectly, though admittedly all I do is add air.  I have never disturbed any connections since new.  I suspect the first time I touch them, I will have issues.  I learned long ago that tire rotation is not worth it for motor homes.

On other RV forums, people use various varieties of these.  The best kind is not an extender, but a valve that is shaped like this in the first place.


For such extenders, metal valves are required, not the standard rubber valves as cars have.  This because the centrifical force from the weight of the extender will fatique the rubber stem over time.  But I think motor homes all have metal valves to begin with because the PSI rating of rubber stems is not rated high enough for our application.

It has been my practice to watch the rear tires for wear and balance but not rotate them (I only flip the fronts every 5,000 miles or so).
This has worked well on all the motorhomes we've had, from 16 to 22.5 inch wheels.

I rotated (by myself) on a class A, once.  Adopted a new policy shortly after I started to feel better - wear them out in place.

the best thing to do with tire valve extenders is don't use them---always fit your wheels with the proper shaped stem so the pressure can be checked--they have always been a problem---they only add more places for a possible leak---always use a quality tire guage with a long stem body---
