PSI With New Tires...
I've been towing a 26' 8,000# camper with my Ram 1500 for the past 4 years with the stock passenger tires. Door jamb says 39 psi. Tomorrow I am having a set of BFG LT tires put on and was wondering ...

When towing, fill the tires up to the max on the tire sidewall.
IMHO, not on the tow vehicle. That could be as high as 80 psi and make it squirly and unsafe.
The best thing you could do is load it all up and then go to a scale. Then you can check the tire manufacturers site for the correct pressure for your weight.
Personally, I would probably just start at 50~60 PSI and see how it goes for both empty and towing. If it's rough when empty you may want to drop it a bit.
It seems like underinflation would invite excessive heat and sway, while full inflation might roughen the ride unnecessarily, but that's a safer way to go. My GMC TPMS alerts at a higher pressure than that for E tires.
Yea, but I dont think they would be underinflated for his truck. The 1500 is considerably lighter than the HD trucks that normally use LT's.
I think I would go 50 front and 60 rear when towing. If not towing he could probably go down to around 40 to 45 in back.
Even my 3500 only calls for 45 in back if running empty.
