Anybody notice a difference in ride quality, handling, tracking, hydro planing between the sport and other 6's? I have the 19's and unfortunately it tracks every groove in the road and hydro planes pretty badly. Not to mention a stiffer ride than I'd like. I haven't tried 17's with this vehicle so don't know if there's an appreciable difference to change. I'm not sure why the auto industry has gone in this direction. Popular demand because they look good and possibly corner better? Any input appreciated. Thanks!
