Viair makes a portable air compressor to air up RV tires.
This little thing makes 150 psi and the duty cycle is 33%.
They make another model that has 100% duty cycle.
This one comes with an extra hose extension and a chuck designed for dual wheels.

Had to pull apart the extension and re-attach it a few times before it started to work properly. The ones we had did not hold pressure, so no leaks.

When we replaced our tires, we had the tire shop use the Tire Man valve stems. Made checking and airing up tires a simple task. Well worth the money. TPMS sensors compatible.

Thank you...couldn't get the link to work but know the ones you mean!

Thanks for the tip! If the cheap one I bought doesn't work out one of these will be on my list.

This is what I did

In order to mount the valve sensors, I had to return to the tire shop to add extensions to the extensions.

The closest ones to work required notching the wheel covers, a tip I found on Google and suggested the shop do it. At this point, I had few dollars and three hours of my time into this project but thought "Problem Solved".

Nope...the sensors were great but just confirmed extensions on extensions double the chance of air leaks...I purchased an RV tire compressor only to find out it had a duty cycle of 5 minutes and could only pump 3 or 4 lbs. in that time. The tires were losing 5 to 8 lbs. per week just sitting in the driveway...so, back to the tire shop.

This time, they checked the second extensions. One, which allowed air last week, would not this week. One of the new extensions would not allow air to pass through either. Apparently, the needle did not reach the first extension's valve. Another replacement had a needle that extended too far, which passed air before going into the valve. I asked the shop where these extensions came from, saying they were the best they could buy and we both agreed on where they probably came from.

I now have 6.5 hours into this and, fortunately the tire shop has not charged me. I have dealt with them for many years and they are very highly rated.

With this Covid thing, I am not planning on any long trips. I will use this time to evaluate this PITA and decide if I should just bite the bullet and replace the outer rear rims with aluminum and throw the wheel covers in the garbage.

Sorry for the long rant, but I wanted others to know how frustrating this can be and, perhaps, save someone from going down the same "rabbit hole".

Maybe some of you have better solutions or ideas? I would welcome them.
I used these valve extenders;

on my E450/Redhawk. I had to drill my hubcaps to attach the brackets with SS nylock bolts in the correct position so they do not hit the rim. But the end result was perfect, no leaks, ever!, No taking off those darn Hubcaps just to check the pressure and they will support my tire safeguard TPMS !

I left my hub caps off. I read on some other forum they tend to fall off. I took one off and it almost fell of when preying off. Works for me so far. I put extenders on my duals myself and they all had steel valve caps on also no problem so far.

Dual tires

I take my Redhawk to the dealer we purchase all tires from. They do it for free and take 10 minutes. Usually tip the guy that does it. Living in a small town helps. Do it before every trip.

Several different sizes on Amazon, both SS and plastic- black and white.
I just bought a set for mine- you just need measurement of hole.

I have the same one. Now I use digital ones because they are much more accurate I notice the angle of the head is hard to connect so I bent the tube a little. I have 3 digital ones and they read within .0 pounds

I thought of that but it makes your wheels- tires out of balance unless they can be balanced on the motorhome

Thanks Bill. Do you, or anyone else have any comments or recommendations?

If your talking about the valve extenders with brackets attached to the hubcap, just put them exactly opposite each other and they cancel each other out and do not unbalance your rear wheels

not only is it an issue putting air in a dually, but now that I have TPMS, I doubt I could get that silly wrench in there. I will ask next time for extensions, they have to remove the front tire to get to the one behind.

Soul- look at the bright side.

The previous post that had the SS reinforced valve extensions. My dad had them on each of his three motorhomes. No function issues, no balance issues.

I recently bought an aftermarket TST TPMS with 6 sensors that go on the valve stem.

The aftermarket seems worthwhile because I have three trailers plus pull others. I can move them to whatever I'm towing and program each trailer separately.

If you pull a toad or a boat, add a couple of sensors.

That's the plan. I have ordered the SS extensions and already have the TPMS. I went cheap on the ones as they do not allow for more than 6 sensors. But I will move them over to my truck and boat trailer when I upgrade to the ones you posted.

Problem solved...order these:

https://yourtireshopsupply.com/manuf...66/duallyvalve

They are not cheap "$120.00" but if you read all of my frustrations in this thread, I would have saved money, frustration and time if I had just bought them in the first place.

Even my local tire shop was tired of seeing me and, because of that, installed them at no charge.

My TPMS works great, easy to add air and best of all, NO LEAKS!

A final thought...this solution, and ones like it, should be a "Sticky".
