The Michelin run flats that come on the new Corvettes are much better than the Goodyear run flats of previous generations of the Corvette. People that switch to non run flats of the same exact Michelin tire say they'd be hard pressed to tell the difference in ride quality. So I will stick with run flats on mine, it'll give me peace of mind on long highway trips. I ran both my C5 and C6 Corvette with non run flats, and never got stranded but I was always worried about that happening, so there is no need for me to continue to press my luck.
