I think a lot depends on your wheels. Dually valves are sized just like tires are sized. You can put a 9R22.5 on a 22.5" x 6.75" wheel, but you can't put it on a 22.5" x 8.75" rim. I think you might find the same thing with the Dually Valves. I have older stud piloted 22.5" x 6.75" which do not accept the newer style Alcoa valve stems, so this may apply to the Dually valves too. Best to call Dually Valve with the manufacturer and manufacturer part number of the wheel and ask them. Dually Valve has all kinds of wheel configurations depending on wheel age and wheel size.

Also when installing any TPMS, you want to make sure that they do not rub on your aluminum wheels. Believe it or not they will rub right through the aluminum polished finish of the wheel!

Tire Pressure Monitor System? YES, they provide real time information relative to pressure, and some systems also provide temperature. Good investment.
AND YES, tire pressure monitors can be placed on the Dually Valve stems. I have been running them for six years, and on two different sets of tires and they work just fine.

They (dually valves) are solid, metal valve stem replacements, so I can't think of any reason why you couldn't put pressure monitors on them.

Disadvantages? One is cost, they are a bit more expensive than extensions (although probably 'bout the same $$ as Crossfire). Other disadvantage is installation is a bit more involved. They are a complete replacement of your valve stems, so rear wheels have to be removed and tires must be dismounted from wheels to put these on. A local tire shop did the install for me for around $40.

When I installed my tire pressure monitors I had a lot of trouble with the extensions on my inside duals.. My best solution was to simply to remove them and put the monitors right on the valve stem. When I need to change the pressure I remove the monitors and screw the extensions back on for the change. I do have to lay on the ground and make sure the valve stems are in a position I can reach. Sound like like a lot of work but I usually only have to do this two or three times a year. P. S. I love these monitors as I can check my pressure on the toad along with the motor home. If I forget it warns me!

I put the dually valves on our prior MH and had great service from them for many years... much better than extensions. I too had looked at crossfire, but decided the simplicity of the dually valves was better.

...I can recommend the Heavy Duty Trucks - Valve Stem Extension Stabilizer Kits that Alcoa Wheels sells for their aluminum wheels. You can use them on most wheels that are on motorhomes.

..Those are valve extension stabilizers. If you're using a valve extension, you still are adding a potential failure point, where the extension screws onto the valve stem.

With the Dually Valves, you get a complete valve stem replacements for both inners and outers as well as a rubber piece to hold it in place. Not extensions. Much better solution, IMO, and less prone to leaking.

Pat, this is almost exactly what you said in my other thread, about why you did not recommend dually valves. I and several others asked you for clarification, but you never responded in that thread.

I think your note here clears up the misunderstanding, and the mystery from the previous thread: You mis-read what we were talking about in that thread, and thought we were talking about Crossfire, not Dually Valves. Soooo, your son, and the company you retired from had issues with Crossfire, NOT Dually Valves.

Glad we finally got that straightened out. :)

I highly, highly recommend Dually Valves.

Just installed them (dually valves) on all 4 rear tires on our MH earlier this summer. Really am glad to have eliminated the extra (4) tire failure points that extensions create. Also like how it allows me to check, air up all 4 back tires very quickly and easily, without even having to remove the wheel covers. No need for any special chuck or gauge anymore, either.

I used to use solid U shaped extensions on outers, and braided extensions on inners. One of the U shaped extension on outer dually tire get hit with road debris, knocking it loose. It caused the tire to go almost completely flat. Right after that, I put the dually valves on. Wasn't going to tempt fate any more, haha. :)

I looked at the Crossfire pressure equalizer units like you're talking about. Am not crazy about them for various reasons, mostly 'cause I prefer keeping it a bit more simple.

On edit: See my thread HERE, where I discussed this before, and decided to go with Dually Valves.
