235/85/16 on our trailer. Stepping up to the “G” rated Greenball Towmasters the best tire I’ve ever had here in tire he77! I’m actually on my 4th season on these, but I have cheated and stored them inside from May until Sept. prior to these I’d never gotten through the 3rd season on any E rated tire we ran. I’d guess we have probably 15k miles on them with two SoDak trips, and numerous Phoenix and Famoso treks. Ours is a leaf spring trailer and I think they put a longer hanger on the frame to accommodate. 6 lug 5k axle.

Wes…. Maybe you could get one of many RV places down there to accept a cash deposit to borrow a tire wheel assy and mock things up. I’d bring one of mine down that way but they’re pretty big.
