Ahhh, ok. So, the airless extensions takes care of the inner dual OK, but probably can't be used with the outer? For that one, you are using a trucker double ended gauge and air chuck.
That would not work for me, as I could not get ANY of the double ended pressure gauges I ever tried to work on outer duals. Never could get the right angle to make it seal on the schrader valve, even after removing wheel covers.

Will, I really do not understand why you cound not get any of the double ended pressure gauges to work? I have had trouble with the Straight-on 30° reverse which you commonly find in parts stores. There is also a Straight-on 180° reverse gauge where the reverse gauge is straight in line behind the front gauge, and not off at a angle like the more common 30° reverse gauges. I can't find a good pic of this type gauge, but can find one of the similiar air chucks:

The chrome is the 180° reverse and the black is the angled 180° reverse. My wheels hand holes are only 2" and will not allowed a 30° reverse chuck or gauge to work. Just not enough room to allow that angle. But a 180° reverse chuck or gauge work just fine in the wheels little 2" hand hole. Alcoa Wheel sells both of the 180° reverse chucks and gauges.
