Ok, non existant tread left. Kept telling myself and my co-driver - sure they got another lap in em...we think. FWIW the safety steward and multiple national caliber drivers were all monitoring us after every lap. We finally called it a day even with times improving as it was a practice session. The one tire has metal showing nearly all the way arond. The other was already flipped and has nylon showing on both edges.
