i haven't measured but they definitely clear, no rubbing or scraping, and i have run the car hard at sebring and several autocross practice days with these wheels. i read on these forums where people had 16" snow tires, and found winter packages at tirerack for running 16" steel wheels and snow tires, that's what gave me the idea to try the 16"s. for competition tires, the 16s are much less $$ than the 18s, and i'm not competing with this car just having fun so i was trying to save some $$.
