valve extenders

Maybe that is what I should have said to start with-----------the Schroeder valve on the inner dual stays there when you put this extension on. The valve isn't taken out like with a regular extension.

Thanks for the clarification, I must have had a brain lapse and did not realize they worked that way.

You're right, extensions like this would not have the risk of leaking, as long as it leaves the Schroeder valve on the tire closed (except when you put a pressure gauge on, like you said).

Would they reach far enough, though, to allow you to check air pressure without having to remove wheel covers? Could one of these be used for the outer dual, and be turned 180 degrees and pointed out so you could get to it (without removing a wheel cover), and still work when turned that tight?

If the answer is 'no' to either of those...then I'd still have to say the DuallyValves are the better choice. That is, assuming you can find a dually valve made for your tires/wheels. If not, an extension like this would definitely be the next best choice (and a lot less expensive, too).

How do you measure to get the right size? Someone told me that you couldnt use the size on the tire but had to measure the tire diagonally.

How do you measure a tire diagonally? :W

..But they can work loose where they're screwed onto the valve stem, and leak there. Thats how one of my extensions leaked, and made a tire go flat pretty quickly.

With solid valve stem replacements like DuallyValves, you pretty much eliminate that risk, potential failure point.

Here's my suggestion: Do yourself a favor, save yourself the risk of air leaks and skip any kind of extensions altogether. I know many use them for years without a problem, but IMO they are just a leak waiting to happen. I had extensions less than a year before one of them got hit by road debris, knocked loose and let the tire go flat.

Save yourself the risk of that ever happening, and get you a set of Dually Valves and be done with it. Complete, solid valve stem replacements, not extensions. Can check, refill with air all of your tires (inner and outer) very easily, without any special gauge, and in many cases without having to remove wheel covers.

I just put these on my MH, and really like them. An easy, simple, fool-proof solution to an easy, simple problem. Thats what I like. :)

I had them installed when I bought new tires 3 years ago. They make checking and adding air so easy I wish I had done it years ago.

They have a stabilizer that fits in the hand hole and provides good support for tire pressure sensors. I had problems with that because of the flexible extenders that came with my motor home when I bought it new in 2004.

be prepared for eventual leaks.

Most truckstops will have any size you need, Flying J, Pilot, etc.

The best flexible extenders are these. There is a wire inside the hose that operates the inner dual schrader valve. Thus, if the hose breaks, no air is lost from the inner dual.
