2014 Corvette C7 Stingray
From The New York Times, Nov. 15, 2013
... After spending some quality time sliding around the Black Lake testing area at General Motors’ proving ground in Milford, Mich., I concluded that buying a ’Vette without the Z51 package would be like getting a puppy without a leash. If you spend a little bit more for a leash, you’re going to have a lot better control of that puppy, right?
And the Z51 package is a bargain. For $2,800 you get performance gearing, a transmission and differential cooler, bigger wheels and tires, bigger brakes, a firmer suspension, the dry-sump oil system and the pièce de résistance, that magic differential.

I agree that the Z51 Package is superb, but
there appears to be a lot of confusion regarding running the C7 OE tires in the cold climates. Unfortunetely Michelin is not stepping up to the plate by manufacturing their Pilot Sport A/S Plus in a ZP version for the C7 with Z51 package. Perhaps with your vast contacts you could get to the bottom of this issue for us. The latest reccomendation from Chevrolet is to run Michelin Pilot Alpin PA4′s – also not run flat technology!
Peter, I was looking up the exact issue with those tires online when I found this post. I couldn’t agree with you more. I had those tires earlier in the year and there would always be an issue with them: the air running low, not handling very well, etc. After a few months of taking it back and forth to my local garage I decided to look elsewhere.
