i know robb and maby a couple others are running 29.5" outlaws on there foreman 500's without a lift. if they can fit them im sure you can fit what you want. they proubly did have to cut a little bit though. on my rubicon i had a 1.5" lift with 27s and when i would turn real sharp sometimes they would rub on the fender supports in the front fender supports.
