I'm running 8" rims. The tires just barely stick out past the fenders. My tread is very mild though. I think you'll need to run 14.5" tires to run 10" rims, but check with the tire shops.
Have you seen the combo that CK5 member IGOR is running? He has 17 wheels with 37" BFG's. Not sure how much lift or how wide the wheels are, but I really like the looks of his set-up.
