Goodyear quote — Stu Grant, Goodyear‘s general manager of global race tires: "This is one of the more exciting weekends of the NASCAR season for us at Goodyear.  Not only is it 'Throwback Weekend‘ for the sport, we also have the Goodyear 400 Cup race on Sunday.  Goodyear and Darlington both have rich histories in NASCAR, and we are very proud of that as a company.  On the track, Darlington is a high tire wear track so tire management will be important for the drivers, and the pit crews will have a lot to say about how their teams perform with four-tire stops all day long."
