I don't think they have put out the actual size yet but this is strainght from the press release.
The Corvette Stingray rides on new 18 x 8.5-inch front and 19 x 10-inch rear wheels, while models with the Z51 Performance Package roll on 19 x 8.5-inch front and 20 x 10-inch rear forged aluminum wheels. New Michelin Pilot Super Sport run-flat tires developed specifically for the seventh-generation Corvette deliver comparable levels of grip than the wider tires of previous models.
Here you go.If someone gets up close to the new Vettes, please check out the tires sizes, front and back and let us know what they are, please?
I'm guessing the aftermarket will love selling all those NEW wheels !:z1-2:Just my 2cents, but I like wide tires. Maybe I'm just old school.:wheelchair:
