though the tires are not the original. in the older dodges there was a recomended tire pressure rating leaflet in with the owners manual.
this leaflet covered min and max tire pressures with load ratings through all cab sizes and bed lengths.
if it is required ill find a way to post it here

That leaflet would specify different pressures for different truck configs and conditions. For example, 265/75 would get lower pressure than 245/75 would. Loaded gets more than empty. Hwy gets more than in town, etc.
The leaflet recommends 45F/40R for running empty around town with 265s. It says to add 10psi for sustained hwy speeds.
I generally run 55F/50R (the "hwy setting") all year round, but will adjust based on how the tires are wearing. I they wear a little more in the middle, I'll drop the pressure; wear toward the edges will get more pressure.

Tire pressure is key to long life. I have some load range "D" BFG's on my 12v, I run 65psi (max) and have had no ill effects. I have never owned a dually, so cannot comment on them.....but at work we run max tire pressure for the tires in everything, because we know the customers that rent our trucks either load to the max, or overload them. The chaulk deal will get you close, then you may have to add or remove pressure to fit your need on load...etc. I also rotate my tires every 5000 miles and cross them to the back, keeps those tires nice and flat on the treadwear, again this does not apply to duallys or directional tires.
