There's a guy in my town sporting 20x9s un-bagged, no rub (except under heavy load) on his mn-12. 18x9s are as big as I would go personally, I would say the 10s would rub, and the backspacing will be greater, causing the tire to stick out slightly from the fender well. Rolling the lip of the fenderwell will be necessary and even then might stick out slightly >>>> 17x7,8,9, or 18x7,8,9 are my overall recommendations for proper "bolt-up" fitment with minimal hassles.
