For the recent past, Corvettes came out of Detroit with Goodyear Run Flats. The stiff sidewall helped carry the tire in the event of no air pressure but also contributed to a stiff ride. many owners derisively referred to them as run craps.
Many owners actually used regular speed rated tires and risked a flat tire or carried a small portable compressor and a patch kit. Some switched to Michelin’s version of the run flats – the ZP – Zero Pressure
For 2014 the Corvette Stingray (the C7 generation) will sport Michelin’s Pilot Super Sport ZP. These tires will have the same size but should offer a smoother ride. It’ll be interesting to see what the new owners say, and why Goodyear was dropped.
