Got a Military Connection? I took ours to the local Navy base's Auto Skills (Hobby) Shop. I thought they'd "rent" me their tire machine, but they wanted me to have them do it for hire. Also wouldn't handle the RV itself. So when I say "took" I mean removed from RV and carried in using another vehicle.
I can offer a couple "self help" ways to "break the bead down" far enough to install the Tire-Man valves. That's if you want a DIY solution. If you do, PM me so I don't miss it.
A couple of our tires were worn from being Toe-Out on the front, and I wanted them flipped on the rims before moving them to the rear duals. So I got benefit from their Dismount, Mount and Balance charges. They did not charge extra labor for the additional work needed for my custom stems.
My personal belief is it's not essential to re-balance IF the tires were in good balance before. The custom REAR valves have a heft to them, but as shown in CD's photo, they get mounted opposite each other. And to me, the custom front valves just aren't heavy enough to require re-balance just because of a valve change.
I sound like a broken record, but YOU WILL LOVE THIS UPGRADE! Tire checking for me is now a pleasant task that rewards me by showing that I still don't need to add air. Our spare kept going down, with its OEM "high pressure" rubber valve. It doesn't any more.
