"LT" tire pressures on Expedition
I moved up from "Heavy Load" tires on my Expedition to real "LT" tires. Max air pressure on the new tires is 80#, max pressure on the heavy load tires was 50#. I always ran my other tires at max press...

What is the pressure rating for your wheels?
Thats a good question , I dont know. I have the stock 20" wheels on my truck. I used a air pressure guide for a tire installer and it looks like if I use 50 - 55# of pressure I should get all the capacity I need. (in the neighborhood of 2,335-2,360# per tire).
I also read that if I go above 60# I may blow out my valve stems. I think I will run at 50, maybe 55#. The stiffer sidewalls should make a nice difference.
I think you are figuring right to run tires at 50-55 psi. Since you can compare how the trailer towed before, to how it tows now, you can adjust accordingly. Yes, the wheels will have a load rating, and tires/wheels designed for 80 psi, normally have higher rated valve stems. IMO, if you need more psi, due to handling, wanting stiffer sidewalls, you should be good to 65 psi, with no worries.
