The five and six hole steel wheels and the 10 hole alloys for the Gen I are 15x6. With 32x11.5's, I encountered rubbing in the front inner fender wells and some on the bumper ends. At full fles, the rear tire would just kiss the frame. With a taller, narrower tire I would still expect slight clearance issues on the front (steering box on left, sway bar on right) and inner wheel well contact in the rear when flexed.

With my 33x12.5's on a slight ramp:


When in an actual loaded flex condition, tools aboard and crossing haul roads, I observed a little contact on the outer lip of the rear wheel wells and additional self clearancing of the front bumper ends. Hope this helps. <img src="/forums/images/graemlins/kewl.gif" alt="" />
