Yellow Corvette Cup C5 race car on display at a trade show with promotional graphics for the NASA 25 Hour Race.

NASA announced its selection for the spec tire for Corvette Cup back in December 2025. Tire sizes for the class reflect a square setup at P315-30-18, which are available to Corvette Cup participants for $370 apiece from NASA’s official tire supplier TrackDayTire.com.

Now we are debuting an innovative new contingency plan that racers are going to love. When there are five or more starters, first- and second- place finishers will win one free tire, as will sixth- and 10th-place finishers. This program will spread the benefits throughout the grid.

Those positions will receive Continental Tire Victory Vouchers, all of which will be handled through your profile on DriveNASA.com. You register once at the beginning of the year, upload pictures of your car showing proper decal placement. When it’s time to claim a contingency, your eligible events are already there waiting for you. Just enter your finishing position, number of starters, and a link to the official results. You can track your award status right in your profile.

“Given the incredible durability of the ECF tire, and the generous contingency program we created with our partners at Continental, it could be entirely possible for drivers who regularly finish on the podium to buy just one set of tires at the beginning of the year and win enough to carry them through the whole season,” said NASA CEO Jeremy Croiset. “For drivers who finish off the podium, it’s still possible for them to earn tire vouchers. We believe it’s going to be a great program.”
