Thread Too Short on Inner Tire Valve Stem

I recently bought a small class C. It's on a Ford Transit chassis. It's the first vehicle I've had with dual tires. Both the inner and outer valve stems are quite accessible. This makes me think they are set up with dually valve stems.

The problem is on the inner valve stem. The length of thread showing is half what I'd expect. I can't connect to it properly with a gauge. There is a nut on the stem that presses against a flat rubber piece. The nut covers half the valve stem threading. I want to see if someone can tell me if the setup is wrong where I need to have someone look at it, or if I just need a different style tool to check tire pressure and to fill it.

I'll try to attach a picture here.

    Good food for thought so far. I appreciate it. It seems like a call to Borg or Tire Man is a good idea for a proper long term solution even if they don't have one now.

    There is a Camping World nearby I can get some opinions from. There's also a Ford truck/RV shop I can check with if needed.

    Thanks,

    I would suggest doing what klutchdust suggested,and see what the purpose of that nut and rubber bushing is. Just a WAG but it may be that they put rubber valve stems on the wheel and the bushing is there so they won't move when inflating the tire which is the cheap way of doing it.

    They should have metal ones,such as Tireman or borg. Both don't list ones for a Ford Transit. You can call Chuck at Tireman and he can tell you if any of his products will fit your rig, he is very helpful and will answer questions you may have.

    I would deflate the tire, remove the nut and rubber bushing to see what their purpose is.

    Dually Valve (Borg) and Tire Man sell custom valves for motor homes. I don't know if they've added Transit. Camping World sells Borg, maybe they can help.

    But I'm wondering if your case calls for only a longer ordinary valve for your inner duals.

    Can you check the rest of your tires easily?

    If that rubber bushing has a retaining ridge on both sides, it'll stay in the wheel and support the valve. You could probably remove that nut. The valves cited above have those "stabilizers" but they only snap into the wheel. They do not have a fastener to the valve.

    I don't know if the Transit uses the typical .453" hole used on cars and light trucks (like Ford/Chevy Class C) or even the .625" truck type. They might use something special. Special meaning Odd to some.
