Have you weighed the rig? Four corner plus front and back.
What tire pressure are you running?
I have not weighed it but the sticker says 9400lbs unloaded. The tires are load rated E. The fronts are at 55psi but I can't even see the rear valves to get a pressure gauge on them. There must be a way to measure the rears?
As with most (all?) duallies, the valve stems on the rear are in between the two wheels. I'm assuming you have daullies; it sure looks like it from the picture, though it's hard to tell with absolute certainty. If the chrome things are wheel simulators (i.e. hub caps), it may be easier to get at them with them removed. The ones I have, and others I've seen, are held on by two of the chrome lug nuts, the remaining ones being fakes. It's not hard to tell which are functioinal by tapping them gently with a wrench or something and listening to the sound.
You do of course need a dual head tire gauge to get at the valve stems of duallies. At least with the Ford wheels, the ones with a straight-on end chuck, rather than an angled one, seem to work better. The angled ones are somewhat more common, though.
It is a dually. I found an extension kit that may help.
