Goodyear Quote -- Mark Keto, Lead Engineer, Stock Car Tire Development: "Goodyear's tire set-up for Texas was first introduced at the 2003 season finale at Homestead. As far as how this combination compares to what we've brought to Texas in the past, this is the same compound as last year with a new, more compliant construction."
