tire valve-who knew?

anyone with dually tires ever have problems putting air in the outer rear tires? valve stem faces in and is impossible to access without a 2 ended air chuck or taking the wheel cover off. my rv dealer just told me about and installed a 135* valve extension which faces out and extends past the wheel cover. now i can easily pull into any gas station or use my own compressor. i never knew. is this old news to you old timers?

    Try that with doubled ended crows foot tire inflator with your compressor
    In the mud in a campground, or anyplace else
    And you have to have your own system
    Won't find one that the gas station with the little air station
    And
    A real pita squatting there holding that thing while trying to get that much air in a class A tire

    I vote for the extenders, or valve stems turned out and easy to reach


    80# or 100# I would not spend $ on any type of extension as I don't have any issue with the OE system. Push or pull no difference to me.

    Yes, this is old news...and has been discussed numerous times on this and other RV forums.

    The preferred solution is Borg Dually Valves.

  • Our Motorhome came with valve stem extensions, the braided steel ones. The one on the street side worked fine, but the one on the curb side some times would have trouble airing up or checking tire pressure. I adjusted that one and re-installed and it was fine after that.

    When we replaced the tires last year, we purchased a set of Tireman valve stems. These are a one piece valve stem, not extensions. They are pricey, but they are worth the piece of mind and the ease of airing up. Since we had them installed with the new tires, we weren't charged extra for installing them.

  • I ha 2 flat tires using extenders with rubber valves. After that I found out about metal valve stems.
  • I bought a new set of 4 braided extensions from Amazon for $20. They are about 6" long
    and come with a clamp to bolt onto the rims (inner holes). I just took the
    old rubber ones off which looked to be 20 years old and they were still good
    but felt it was time as I got new tires.

  • I have put extensions of various shapes on several rv's. with metal valve stems I have had no issues. Rubber stems, different story. Make sure the extended are on snugly but not overtight. Too tight will crush the "O" ring but too loose will leak.

    Check the air pressure a few times after installing over the next several days to make sure all is well and then have happy travels.
  • Just make sure the extension is supported in some way. That much weight on the end of your original stem without being attached to something could cause a problem.

    Not knowing exactly what you have, it may not be an issue but it is worth checking.
