Goodyear Quote -- Mark Keto, Lead Engineer, Stock Car Racing: "This is a brand new tire set-up that we're bringing to California this week. It follows along with some of the changes we've made for the 2004 tire lineup, with a more compliant sidewall construction and softer tread compounds on both the left- and right-sides of the car. While this is the debut for these tire codes, Nextel Cup teams will run them at six tracks, making this the most popular combination we will run this season."
