Checking Inside Dual Tire Pressure

I've been having a devil of a time checking the tire pressure and adding air to the inside duals. When I replaced tires, they put long extensions (about 7 inches) on. The extensions didn't extend into the hand hole and didn't even line up with the hand hole's. I reach in and bend them over a bit and screw on a braided flexible line to check the pressure and add air when needed. They're the airless kind that have a rod that pushes the valve stem in the tire's valve. I sort of like the fact that it's mechanical and not a pressurized extension. Recently I noticed wear at the tip of the extenders. They've been rubbing on something. So I need some slightly shorter or a better solution. Without the extensions on, there is no way I can see or get an air chuck on the short valve stems. I looked at the Cross Fire system and some other things designed to help but I'm been trying to stay away from the flexible lines. There's got to be an easier way to do this.

Agree with UFO Pilot; the Dually Valve Stem extender or equivalent are the way to go. I had mine installed by my dealer; they make checking pressures and airing a breeze.

I had previously looked at the website. I see a Workhorse kit for the 19 inch wheels but didn't see workhorse mentioned with 22.5 unless it's this Kit... DUALLY VALVE STEMS FOR 22.5 INCH STEEL WHEELS DS4SST W HAND HOLE 4 1/8" X 3"

These look like replacement stems and the tires would have to be broken down to install. Is that correct? Just out of curiosity, the stems are $120 on the website, how much were they installed at the rally?

My rims are 22.5", installed price was about $130 total.

I've got a straight air chuck. I purchased an inflator and air chuck at Valve Pal.

Talk to Bill at Duallyvalve Kits for Wheel Sizes 22-24"
I just had the tire stem valves installed on my Adventurer for $75....don't skimp on some cheap extenders...you have a many thousand dollar MH...spend a few bucks more and do it right. Stay away from extenders or flexible lines...they may look good for right now but from what I have read online they are doomed to eventually fail....the choice is yours. Good Luck!

I think ours were about $150 bought and installed at my local tire store.

Thanks to all for advice and suggesting "Dually Valves." After wearing out google, I'm going to purchase a kit and have them installed at some point that I find it convenient and a place I feel comfortable with. I called Bill but he was out. I'll try again. Looking at the photo of the kit that should fit my W24 chassis, it looks like the stems will need to be bent. I'd prefer to have them installed at a rally where the installers are familiar with my coach. I didn't see any close to me through the end of the year. My other choice is to take the kit to the local Goodyear truck tire dealer (Wingfoot) in Jacksonville and see what they say. But at least now I have a plan. Thanks

Cross Fires: Crossfire Dual Tire Pressure Equalization System., or Cat's Eyes: Link Manufacturing Cats Eye, will solve your problem.
I've had the Cat's Eyes for 12 years, (90k+ miles).

I agree with Mel s. The cats eyes will keep both duals at 100psi equalizing the pressure on both. You can just glance at the guage and you can see if you need air. You can get them at truck stops. I own a fleet of commercial trucks and these things work great. You only have one valve to fill for both duals!

checking tire pressure inside dual wheel

We have a Newmar, came with flexible inside wheel extenders. These had problems & hard to fill, installed duallyvalve solid valve (not extension) going thru outer wheel. we have steel wheels & they had to furnish different rubber guides for outer wheels. yes must break down inner wheel to be installed. One of the best things we have put onto the coach. you can reach duallvalve 1-800-300-2674.
