Ram 3500 DRW tire pressure
So I just upgraded from a 26ft tow behind at 5500lb to a 40ft fifth wheel that comes in at 13400 empty. I usually run 80psi all around. Does that need to change with the addition of the fifth wheel?...

Cummins12V98 advises run the newer RAM dually front tires at 80 all the time. Rears can be aired down to mid 30 to improve the ride empty. What does the door sticker state for full load? Should be around 65 pounds for the rear. Chris
I run 80 ALL THE TIME on fronts per door jamb. 4wd Cummins and Aisin add up!
I run 35 solo. Plenty of capacity. With full RAWR 9,750# I run 65 rear per door sticker. With the ops lighter pin I would know loaded rear tire weights and use weight inflation chart plus 5psi. I'm betting 55-60 psi will be more than enough.
