Well I respectfully disagree and believe the safest and most effective tires for your RV if you can use E rated or G rated would be to buy the 14 ply Goodyear G614's. When our springs broke in Oregon last summer, thankfully the 14 ply tires that can be run at 110 PSI instead of 80lbs PSI made the difference in safety. Look behind the tires and see the embossed letters on the inside of your rim. If the letter G is there I would strongly consider the tires I bought. I know a few people with your model that installed the Goodyears and love them. Fyi, I went from 235/80/R16's to
235/85/R16's without any problems. Anyone who bought the excellent E rated Michelin tires, I would like to know how the rig handled after your springs and suspension broke vs the G Rated which has stronger ply by far.
