I think the'll fit,they will fit 35x12.5 on 15x8. but not for wheeling.

The front of the turtle when it's bound up crossing a ditch,will stuff the front so far that when the tires 33x12.5 are turned there is about a pinky finger clearance at the top of the front fender.

If you get rid of "The cuteness" <img src="/forums/images/graemlins/smile.gif" alt="" /> and trim the upper part of the fender then they will clear and turn.
The only issue in the back besides maybe rubbing on the door will be a 10" wide wheel,then you'll crunch the tire,like the fellow in the white rodeo with 32/33" did at Callantee,the crunch was bad enough to stop the tires...
Maybe I'll throw some 35's on this weekend and snap a few pics.
