up until today I had 33/12.50s, 15x8" wheels/3.5" backspacing with about negative 1" lift (old stock springs + all my tools & junk)..... my front fenders are cut pretty dramatically and I bashed the wheel wells all flat and tire friendly- in the rear I cut about an inch above the pinch welds all the way around, drilled the welds out to remove the cut off strip and then took the bfh and bashed the excess wheel well lip up to the cut line, did a little trimming and welding.... ~voila~ ghetto tubbed! the fender flares took some imagination to re-attach, but I have never been thought to lack imagination. it didn't cross up nearly as nicely as with the 30/9.50s I had previously (DUH) but articulation in the mud isn't exactly critical
