I upgraded from the Goodyear Run Flats that came with the car to the Michelin Super Sports. This was a transformation of the car's handling, ride and general road stability. The car now handles rides and performs the way it should. If you have a Corvette, do yourself a favor and get rid of the handicap of the Goodyear EMT's or Run Flat tires. No more darting on uneven pavement, too soft handling on twisties and general feeling of instability. Now I know why the Z06 and ZR1 come with Michelin's. Don't hesitate to make this choice.
