If you want to do any wheeling, and you don't want to be rubbin' like crazy, I'm pretty sure you need to put at least 2" on there to clear your 32"s. I can still get my 32" BFG AT/KOs to rub with NO mudflaps, on a BIG bump while cornering, WITH a 2" BL. They never rub on the street or pulling into driveways, though.
