My original Mission Tires were E rated 235/80/R16's, and my new Goodyear G614's are 235/85/R16's and they fit just fine. I have 16" aluminum rims. And as a bonus, my rotochoks fit just fine. The spacing is great and the ride is superb. Like I said before, when my leaf springs broke, I wonder which hospital I would be in if I had E rated tires not 14 ply G rated Goodyears on. I was amazed that even after the frame sat on my new tires, they were in fairly good shape, with alot of sticky rubber but still usable. I did have to change one tire, but it didn't blow under that pressure which can't be totally attributed to my wonderful karma.
Lonestar, keep those barely used Goodyear 614's.
