Year, Model, Performance or Base
Proper O.E. tire size is determined by options or changes by the manufacturer. This may dictate tire size year-to-year. Next to consider is the model for the Corvette tires you need. Corvette models include coupe, convertible, Z06 and, returning in 2009, the ZR1.
Now, look at whether your Corvette is the standard model or has the performance handling package. Other considerations include whether you will be driving your Corvette in snow, and how important handling, ride/noise comfort and tread ware are in your priorities. These latter are important when considering tires other than O.E. tires.
