new tires on TV

Hello I just put on new tires on my TV they are nitto 285/50/22 and have an E load rating. My question is what is the proper tire pressure I should be looking at for the stock tires which were 265/60/20 say the fronts should be at 60 while the rears should be at 75. Right now I have both the front and rears at 60 and it rides like a dream but when I go to tow the trailer should I raise the tire pressure up to 75 to compensate for the weight? I have looked everywhere on line and can't find the right tire pressure but my dealership filled them up to 60 on all 4.

If you are going to load the tires to close to their maximum weight carrying capacity (which it says on the sidewall), then you need to air them up to their maximum cold pressure, or else you have to derate the capacity. 50 profile tires are getting to be pretty short in the sidewall, and it is very easy to bend a rim or pinch a sidewall hitting a bump. (I've done this on my sports car with 40 profile). I would run them at max cold pressure while towing.

On my Ford SD the front are 55lbs and the rear I run 70lbs.

I learned the hard way not too go to a oversized tire (285/75R16) from the 265 size because of the sidewall roll I was getting when towing, so i went back to the orginal 265 size tire.
