Looking for comments on the use of valve extenders for rear duels. Have heard pros and cons from friends, now looking for comments from RV'ers.

Have not used valve extenders, but installed Dually valves on my duals. In two years use they have performed without problems, and would recommend the dually valves rather that extenders. Dually valves cost more, but are a better solution.

Valve extenders are not recommended. I've had two Freightliner Chassis, the first one had aluminum wheels, current one has steel wheels. Extenders were not needed on either one.

Dually Valves. AND, they work fine with TST monitors.

Hi JDG,

I've had valve extenders on every coach I've owned since 1978. That is more miles than I care to count. I've never has a problem with the valve extensions or the connection to the wheel. I also use a tire monitor system with each extender having the monitoring device on the end.

Do NOT use the Airless ones... If the rubber seal deteriorates and mine did in one year, it allows the extender to become out of adjustment and lose air... It cost me a new Michelin X that had less than a 1000 miles on it... $350 gone!!! I highly recommend the ones from Dicor... call them, tell them what you have and they will send the exact right ones for your rig.

Our '05 coach came with the stainless braided extenders. No problems so far. I will replace them at tire change time. Think I will go with dually valves next.

My '03 Winnebago on an '02 Spartan chassis came with solid metal extensions on the inner duals (I believe they are available in brass or steel ...no idea which mine are). I got the rubber stabilizers that fit in the wheel hole (both Alcoa & Accuride make them) to keep the long stem+extension from flexing as the wheel turns at highway speed. I have over 60k on my coach and have never had a problem with the extensions. Topped off with Alligator caps (high pressure dual-seal "air thru the cap"), they make checking tire pressure and/or adding air a very easy experience. I am now using them with TireTraker TPMS sensors, and they are working great.

I have been using 3 1/2 inch solid brass extensions on the rear inside duals for over three years with no problems. I have steel 19.5 wheels with stainless wheel covers, and it sure makes checking and airing the inside tires a lot easier. I think I purchased them at Camping World.

Valve extensions are unreliable. I will never use them again.

Stainless braided on the rear duals. Been fine since 2001. I also have TST monitors which I'd recommend for anyone. The only extender's I've had any problems with have been the solid brass extenders on the 2 fronts.

Where did you get them? Less than 50 would be nice. Would Napa have them?

Mine came with the braided extenders on the rear 22.5 duals. Those have been fine and never gave me a problem.
The front tires, however, were a different story. They came with a brass extender that had a 45 degree angle to it. Both of them leaked even though I tightened them quite hard. I removed them and will not use extenders on the front again.

Personally, I would never use valve extenders. If you DO use them, be sure to change out your rubber valve stems for metal ones.

We ordered a complete set of long, metal valve stems from The Tireman and had them installed by a local tire shop. Note that these are NOT extenders!!!
