Never having owned a dually, I'm looking for the easiest way to add or delete air from my duallys. I had flexible extenders untill my dealer rotated my tires & forgot to put them back on. They don't seem to work very well as they move around when you put the long air chuck on them.

I've read where there is a metal extender, but also read where they can break off from rocks or objects between the wheels. Do you put the valves right next to each other? It seems like a pain no matter how you do it short of removing the tires. Enlghten me please! Thanks, Patrick

 

Just go to your local napa and get ask for a big truck/dually air chuck. While your there get a tire gauge as well. Removing air is as simple as not pushing the gauge on all the way. Really no need for the extenders.

 

Easier to get the inside wheel if you remove the skins.

 

Thanks,I have long air chuck,& a long air gauge from camping world. Taking the skins off is probally a big help.Guess I'm looking for some easy way to a straight forward task.

one thing you want to remember, if you are not running that truck with a load in the back all the time, rear tires should be at 40psi max, i already learned that lesson the hard way, the center wears out if you run them any higher with no load, too much flotation with no weight in the rear end. front should stay at 65psi.

 

i usually ran mine @ 35 psi empty and 60 + when loaded
front 45 empty

 

Get one of these it's what I use, has the gauge built right into it.

I run 80 F, 50 R and the tires are wearing fine. At 80 in the front there's less rolling resistance and the more air the better because the sheer weight of the engine will keep the tread flat on the pavement.

 

I run all six wheels at 70 psi. My tires are OEM General Brand and max PSI as listed on tire is 80 PSI.

I found that on the 07.5, you need to run the tires on the front of the truck at 70 PSI becuase if you don't, then the front steering gets real hard to turn. I think this is due to too much sag in the front tires. After I inflated mine to 70 psi, front wheels got a lot easier to turn!!!!!!

Plus, you've got that big heavy diesel engine up there that adds a lot of weight to the front end. If I run any less than 70 psi, then I can really see the tires start to sag under the weight of the truck.

If your tires are underinflated, then your fuel economy is really going to be hurt I would think.

Whatever PSI you choose, I would go with that number and keep all tires at the same PSI. Makes it easier to remember.

There is no easy way to fill the duals in the back. You have to take off the wheel cover, and poke and hope with a dually tire gauge and air fill chuck. It's not any easy thing to do on stock tire and wheel setup.

I know that Dodge puts more than one brand of tire on their trucks as OEM equipmment. These are just my observations using the General brand tires that were the OEM tires on the truck when I bought it.

Hope this is of some use to you.
