checking air pressure on dually?
i have a f550 and dont know what to use to check the air pressure and inflate the rear tires on a dually. the ste, points towards the frame and the other is int he middle. any guage for duallies that i'm not aware of? and a side note, man, the 550, pressure all around is 95psi. oh, and say it's 30 degrees outside should you fill up to 95 or a little bit less for when it warms up?

You need a truck gauge. They are about 12" long. I imagine you can get one at most any auto parts place, or truck stop, or as a last resort a truck dealer. You will probably need a longer air chuck than 'standard' also.
Tire pressure is supposed to be taken 'cold', so if it's cold, I would go for 95lbs, but that's just me.

I saw one of these on a Brinks truck the other day. I don't know anything about them, but the concept sound pretty cool.

My filler and pressure checker have a double sided valve so you and either push it onto the valve or pull it onto the valve depending upon which direction the stem is pointing. Sometimes I have to squeeze my hand into the rim opening to align in on the stem though.

95 psi seems a lot to me and i have been doing tire for 35+ years. I never go above 50 psi on my light duelly's unless I over load them. than never exceed 65 psi. I run 70 psi in my Log trucks and rock trucks and have less than half the tire where and puncture that my mates do. Think about it. If the duels aren't touching together and the tread is flat on the road That is all you need. If running on gravel roads the softer tire will compress a little when running over a sharp rock that would go through the face of a hard tire. I have clients come in with flat tires on there loaded SUV.s with the max presser of like 65 to 85 PSI and don't understand that a sharp rock will go right through the face of their 4 ply tires. I deflate all there tires to 32 psi, 35 if they are loaded for bear and they have no more flats.

WHY on line? pay the shipping, dont know what your getting, paying too much
The parts store has them, Wal-mart has them, you can get a "duel foot" guage most places that has anything to do with tires or trucks.
As far as the "Duel Dynamics" things, No Way! If you get a leak in one, both go flat. I've driven or been around trucks for more of my life then I care to remember, Ive had blowouts in even the best of tires and I have limped home on one of a set of duels more then a couple of times. If you got one of those things both go flat, Yea, they have a valve in them but..... It was mentioned years ago on the fire engines I am associated with and we vetoed it real quick.
NAPA had a short line that bolted to the outside wheel that worked well, had both stems on the outside wheel. I put well over 200,000 miles on the truck I had them on.
I may be new to FORD but I aint no stranger to trucks big or small.

If you go to Autozone, you can get the gauge I have for my truck. It's made specifically for duallies, and has a good range needle gauge with a little pressure relief button, flexible hose, and a hard end with two openings... one for pressing forward, and the other for coming in from behind.
That may be a little tough to follow, so here's a pic:

IIRC, it was about $15... at Autozone.

Just a thought that your wheels might not be lined up to check the air , when wheels are properly installed the hole (window ) of the outter rim should line up with the valve stem of the inner tire exactly 180 degrees from the other stem , some axles will have a line up pin which lines up with a hole in the rims , some don't have it , or had it but it had been knocked off or fell out--------on another note checkng them can be real easy with a set of equalizers , as a quick glance will show red , yellow or green condition of both tires , they worked real good for me on the 450 dually I had before this 350 I got now that has single rear tires , I know I don't miss the extra wheels at all

i have the 19000 lb package with a dump body. it's is loaded to the max weight (sometime even more unfortunately b.c the guys at the quarry are idiots) every single day with stone, sand or portland cement. i'm a stone mason that is tryign to take better care of my trucks and do the work myself instead of taking it to the dealer. down time kills me. i didnt know about the dual head nozzle things..i actually already own one. but now i gotta find one with a gauge like above.
so, since i do have truck loaded to max, 95psi is indeed good, right?

I run 22 inch tubeless tires on my log and rock trucks. I am always over weight as there is no DOT or scales in my area. I run max 75 pounds and have less flats and longer lasting wear than the guys running 90 pounds. Nobody in the big rigs around here run more than 90 pounds. On yours I would run 70 pounds if the tires do not touch when loaded. No more than 75.
