Tire pressure and temps while towing

I have also noted on both trailers I have towed with the TPMS system on them that the curbside tires will run about 3-4 psi and 5-8 degrees warmer than do the drivers side tires and that's based on starting with 80psi all the way around.
I did contact Maxxis on this and all they could tell was that the tire was designed for increased pres and temps and as long as I didn't exceed the weight rating of the tires I shouldn't have any issues.
