I'm thinking about putting E rated tires on my trailer which has steel modular wheels that are rated :shrug: at 75 psi. The E tires are rated 2830 lbs at 80 psi. Trailer GVWR is 9990 (two 5200 lb torflex axles) and won't be loaded to max capacity ever, but I'd like as much "headroom" as I can get on the tires. I was told the rims could easily handle 80 psi as long as the trailer isn't loaded to the max. Should I run the tire/wheel combo at 75 psi? Or 80 psi? Or...?
