Firestone Tire Performance Summary: Based on data acquired during two separate tire tests at Iowa Speedway, Firestone engineers elected to bring the same tire construction and compound previously utilized this year at Motegi and Indianapolis for the left side of the cars, and the superspeedway spec (Homestead, Kansas and Texas) for the right side of the cars. Temperatures today were 20 degrees cooler than had been predicted, and tire wear was not an issue. In fact, race winner Dario Franchitti ran over a stint and a half (104 laps) on his last set of tires.
From Dario Franchitti, Canadian Club Andretti Green Racing Dallara/Honda/Firestone: "Just a great job here by the Canadian Club guys all day. We took a bit of a gamble there at the end just to extend our lead, and it worked. My car was fantastic, and it was a fun race - pretty physical, though! I had total confidence in my Firestone tires. I told my crew that I had no drop off in tire wear - I said let's just kept going, and the Firestones were great. I think we could have run a double stint on them today."
From Al Speyer, Executive Director, Firestone Racing: "What a challenge this race has been. We certainly learned a lot, and that is always a good thing - to come away from a brand-new track feeling like we have the information and tools we need to make what was a fantastic inaugural race even better and racier next year. Many drivers were talking about cold tires, and there had been some comments that the tires were 'hard' for this track. With temperatures expected to be 20 degrees higher than they were, had we brought a softer tire, they would not have offered the durability that the drivers would have needed to run a stint - let alone 104 laps like Dario ran on his last set of Firehawks to take the victory. When drivers take fuel only on a pit stop, it shows how much confidence they have in their Firestone tires, and that always makes us proud."
