But in the mean time, the right pressure is based on weight and you appear to be categorizing all 4 wheels the same.
Go outside, set your fronts at 50-55lbs (assuming stock ish size tires) and the rears to 35psi and take a quick test drive.
65 is acceptable but stiff up front and still rock hard on the back of an empty pickup.
You would want to air up a bit in the rear when hauling the TT but 65psi will handle the full tongue weight of a wavier trailer than yours AND a bed full of stuff.
50-55(2270 lbs - 2370 lbs) in the front of a dually is way underinflated if it is a diesel truck assuming 235/80R17Es. Front axle of my 2015 3500 SRW is 5120. Dually will be at that or more as most set nose down. The skinny tires on the front axle need almost the full side wall inflation of 80 PSI to handle the static weight of the front axle. I am surprised the Ron was not all over this???
Now for the rears, that tire at 35 PSI dual is rated at 1570 or 6280 for an empty axle that weighs in at 3-4,000. So at 35 PSI one could still throw a ton of stuff in the bed and not be under inflated. Chris
I run 80 fronts on my DRW all the time. Even with 6k pin the front weight increases less than 200#.
