I modified my spare tire carrier to accept a 31" tire, at the same time I did my bumper and gas tank lift. I sectioned it, raised the actual tire mounting point just high enough so it still fits in the wheel, and I beefed it up by gusseting all the corners. But even before that I've had that 31 on there for over a year without any problems. Lots of trail rides and plenty of rockin' at Paragon. I know the mounts are different between the ragtops and tintops, ( my parts car is a ragtop) maybe the tintop is stronger.
