I've got 32x11.50's on mine. The wheels are aftermarket, but I don't think they have anymore offset than stock. The tires rub the radius arms at full lock, but otherwise are fine.
ive got 31x10.50 on my 94 2wd that is lowered 4" front and 6" in the rear and they dont scrub. lol but my buddy has 33x10.50s on his 4wd on stock wheels and they dont scrub either.
