Best Dually Valve Extenders for tires?

[Jleer]

I have a 2014 Sightseer 30A.
What are the best extenders for RV tires?

2 years ago I bought flex hose extenders and short angled extenders off Amazon. I think they were all made in China. I used the flex hose type for the inside duly tires. They worked fairly well.

But for the front tires and outside duly tires, I tried the short extenders but couldn’t tighten them sufficiently to eliminate air leaks. But without extenders on these, particularly in the front tires, it is real hard to add air to the tires since the tire stems do not stick out enough from the hubcaps. Any suggestions?

These worked well for me. Amazon.com

Jleer-

A popular brand of solid valve stem extension is DuallyValve. "YourTireShopSupply.com" (YTSS) sells them. Here is a link to their DuallyValve product Web page.

Some DuallyValve kits come with rubber stabilizers. You may also buy stabilizers that fit DuallyValves separately.

I put solid valve stems on all six tires (two front, four rear).

I recommend you call YTSS to get the correct parts for your coach's wheels. When I bought parts from them in 2019 the customer-service person at YTSS was very helpful, and later helped me out of a bind when the tire shop installed the incorrect parts and threw away the correct ones. Excellent service from YTSS!

Use the correct parts, follow the DuallyValve instructions to the letter, and you should be all set.

I've never found any specific brand, type or shape that would work better on all wheels, so have had to fight the fight each time for each type wheel.
One of the biggest issues I wanted to cover was making sure all the TPMS sensors were fixed solidly to avoid the stress they put on if not attached to something solid.
Eventually I simply stopped trying to find the correct shape of solid stems as there were so many small point that changed what was needed.

I agree with the idea that flexible has their own set of things to worry but I was never able to find a full set of solid stems to do all the wheels. I am willing to accept watching for any leaks that may come up on flexible over a lifetime of searching for others that will fit without rubbing!

My personal choice at this time and assuming I might ever want to set up a new TPMS, I would go for flexible lines and spend a bit more time on them to get the total package done the way I feel it works best.
I find it fairly easy to cut and shape small sections of aluminum angle for mounting the sensors solidly on the wheel simulators. Flexible lines let me choose that spot much better and much easier than any solid stems I have found.
The main complaint on flexible is that they tend to swing with the momentum of the wheels but that is what I see on over the road trucks, so I go with them!

Maybe take a bit to pull in at a truck stop, etc. to just look at what they use and it will lead you to what works for the folks who do it much more than us rookies?

One point that I really liked once I got around to doing this is that I could stop obsessing over the tire pressure and just let the system watch over that pain. I traded off crawling around and trying to air the tires to the correct pressure once I saw how little real effect it had on my overall tire pressure!
Once seeing the pressure change constantly, I stopped trying to keep it exactly right!

Borg rigid valve stems are popular and very well made. I've had zero problems using them with TPMS sensors.

Yes to Borg valves, they have worked problem free for us.

I have a 2023 Winnebago Vista 29V that currently has only extended valves for the rear inner dually tires. I have a new TPMS monitoring system that I want to install but am unable to reach the rear Outer tire valve. Suggestions for this setup on valve extensions?? Thanks!

Dually extended valve stems are a 1X purchase. The sealing washers are replaced at each tire change.

I still go with my post number four above!
While it does take some minor hand tools to cut and fit the aluminum angles and mount them to hold the sensors, I find that is better for me as I can then just get as et of flexible lines that are about right length and go to work.
I hate looking/searching for something that kinda/sorta looks like it might fit, only to get
it home and find the bend is just a bit off. I don't want to settle for stems that are rubbing from day one.

The tools to shape the aluminum angle stock are a hacksaw, file and drill with the pop rivet gun to attach them.
But if not wanting to DIY a set, this may be a start for mounting .

You can buy quite few of these for the price of one set of the other options!
After setting a couple different RV, I started looking at what trucks use and find flexible work well for me.
A point often mentioned on flex is that they leak? But if they are good enough for over the road drivers and you now have a monitor to tell you if they start leaking, is that still way better than driving with none of the bennies of a TPMS?
But I've not had trouble of them leaking, so I'm happy with going for the ease as well as cheaper!

The folks that that looked at my tires recommended cats eye tire pressure system. It connects both dual tires and keeps them at same pressure with only one fill place. There not cheap ($200?) so I don’t have them. When I get new tires next year I may splurge on them
