I choose the 18" run flats on my MSport because of the harsh drive from the 19s. I got that info from a buddy of mine that had the 19s until he put 18" non-run flats. It's a noticeable difference from his vehicle to mine but don't know if its worth the cost of tires, plus the thought of being without a spare.
