Valve extensions

We have a 2019 class c and it is major effort to add/check inside doully. Too many extensions to consider. What do you use..

Dually valve kits for Motor-homes, Busses and 6-wheeled chassis

On my 2017 Greyhawk I use an extension on the inside rear - straight, about 4” (if I remember correctly), no extension on the outside rear, and a 3/4” straight extension on the front. I then add TST flow-thru tire pressure transmitters, so the length needs to be precise. Works good for me. Checking pressure the oldfashioned way and adding air is reasonable with this setup.

Might be a no-brainer, but just to be safe...make sure the inside dually wheels that the extenders are attached to, have metal valve stems. You're asking for trouble if the valve extenders are attached to rubber valve stems. FYI. Happy Trails...

Our 2009 Greyhawk came with valve extensions. The first couple years, they were trouble free. Then one of them became troublesome until I removed the hub cab simulator, removed the extension and tightened it back down. Then no more problems. When it came time to replace the tires, we purchased a set of Dually Valve Stems from the Tire Man. They worked really nice. They made the valves more accessible. Checking air pressure and airing up the tires was made a lot easier. Pricey, but definitely worth it. Since they were installed when we bought new tires, there was no additional charge to install them.

No trouble with valve extenders on two RVs over nine years.
The first set were installed at a local Discount Tire store.
The second, on a new RV, were installed at a truck tire store.
Yes, some people say valve stems leak and a trouble.
We have had none.
And they make checking air pressure a 5-minute task. I check psi four or five days prior to every outing. And if a tire is low, I have three or four days then to have it checked at a tire store.
