Goodyear Tire testing continued Wednesday at Atlanta Motor Speedway as Kasey Kahne and Jimmie Johnson ran an array of tire compounds in preparation for the March 18-20 Golden Corral 500. Mark Keto, lead engineer for Goodyear¿s stock car tire development group, said the second day of testing really helped to narrow the field of potential tire compounds for the upcoming Atlanta race weekend. ¿Today is going really well,¿ Keto said, ¿There are four new tires we¿ve been working with today, plus several from yesterday that are giving the drivers some extra grip and confidence.¿ Engineers also found that even with the new NASCAR rule changes, such as the reduced spoiler height, Kahne and Johnson were running speeds comparable to last fall¿s Bass Pro Shops MBNA 500. Goodyear Tire experts will analyze data from the two-day test before finalizing which compound drivers will run during the Golden Corral 500.
