Did the All-Star Race Kill the Idea of Two Types of Tires in NASCAR for Good?

Tire Management

NASCAR’s made its stand loud and clear in the last few weeks. Tire bleeding will not be allowed. If you persist in trying, they’ll come down hard on you. […]

The only thing that’s slowed down is planning for on-track independent testing, since that’s been eliminated this year. But more time in the wind tunnel, on the seven-post machine, at the computers.
