I'm considering getting valve extenders to make it easier to check my air pressure. But, I'm also considering getting a tpms and thought the longer metal stems would give more support. Any thoughts?

Actually longer stems have less support due to the extra length (unless you add supports). The longer the distance from the valve hole the more torque it adds.
1 foot and 100 lbs = 100 ft lbs of torque.
½ foot and 100 lbs = 50 ft lbs of torque.

Dualy valves are solid metal and come with stabilizers that fit in the handhole
They work great .

i have 19.5 inch wheels and have the original tst truck tire pressure and temperature monitor system.
i am using haltec he 200 90 degree valve extensions on the front wheels and the rear outer duals. i have to keep them tight to keep them leak free.

The great thing about the DuallyValves is that they replace the original valve stems, so no maintenance is required. The downside is that the tires have to be dismounted and remounted to install them and they aren't cheap. I waited until I was replacing the tires (three years ago) to have them installed and wish I had done it years ago. They make it so easy to check and add air. My PressurePro pressure monitors work great with them also.

There is NO comparison. One piece solid stems is the only method.

Extenders of any brand, quality, whatever are just one more place to have a leak problem and people do, then wonder why!

Dually Valves, well worth the investment.

I guress we have a difference of opinion. We used rigid extensions on our old motorhome in conjunction with the TST 507 tire pressure monitoring system. The stems never leaked in over 100,000 miles and made installing and removing the sensors a 2 minute job.

The disadvantage of the long valve stems is you make the inside duals a single position tire. They can't be moved to the front our outer dual position (without changing the valve stem) beacuse the stem will be either sticking way beyond the rim or pointing in the wrong direction. If you use extensions they can be added or removed depending on which position you want the tire.

As for the DuallyValve setup you can't individually monitor each tire.

If there is a Tire Man product to fit your vehicle I can recommend it wholeheartedly.

Big bus type RV's are NOT setup to move wheels and tires around.

If a flat occurs that tire is removed and a new tire is installed on the same wheel in the same position.

My inside dual is a plain Jane steel wheel. All of the others are aluminum wheels highly polished on one side ONLY.

So for me the Dually Stems work great.

For smaller RV rigs it may not. If the extenders work for you, that's great!

EMMV.

There is a term KISS. Keep It Super Simple is the polite expansion.

What is simpler

One: A long valve stem, Just the stem, long enough you do not need an extender or:

Two: A shorter stem with an Extender?

Clearly The long valve stem

These are solid metal stems. Do not worry about the weight of the TPMS sender on 'em, it won't bother them a bit.

You obviously dont know anything about Duallyvalve brand stems. Please check your info before you mislead any more Rver's. Thanks.

You're right. I was confusing the Dually Tire system with the Crossfire system.

I apologize

Dually valve stems are far superior to ANY type of extension. An extension is a patch, and the dually valve is a replacement for the original valve stem. SIMPLE!

As has been stated by others, you do not rotate tires on a motor home. Tires and wheels stay where they are installed and tires replaced as they age out, not wear out because of milage.

TPMS work without any problem using the dually valves.
ONLY WAY TO GO.

I have solid metal 4" extensions on my inner duals, with Alcoa rubber stabilizers where they pass through the outer wheel (Accuride wheels w/Alcoa stabilizers). Solid metal valve stems can crack ...one was on my coach at delivery, and the first replacement they put was also cracked. The stabilizers keep the stems from being stressed (and possibly cracking) by centrifugal force when the wheels are rolling. I have TireTraker TPMS sensors on all wheels. 10 years and 85k miles and never had a leaky extension. I did buy a bad pair of extensions once from a truck tire place, but the problem wasn't leaks ...the long core was too short to trip the valve core on the stem.
