Do not go to a Goodyear store. They spend too much time mounting 60 and 70 profile H and T rated passenger tires. Whether or not they have the equipment, most do not have the experience to mount low profile tires. They would rather keep adding weight than redo a mount and balance. Doing 4 or 5 Corvettes a year does not qualify as having plenty of experience.
Go to a wheel/tire shop that specializes in performance wheels and tires. If they handle 17, 18, 20, and 22" wheels and tires, they can handle yours.
