Fast facts: Chase leader Matt Kenseth could be forgiven for a relatively sour opinion of the tire that Goodyear brought to Kansas Speedway this weekend. It's not that he dislikes the "multi-zone tread" that made its debut Sept. 1 at Atlanta. It's just that the defending race winner at Kansas would have been happier with the status quo. "I would have rather left everything alone, for us, especially after today," Kenseth said after Thursday's tire test. "Today was a struggle, and any time something is new and you struggle where you've had success, you kind of wish you could go back." It's rare that NASCAR changes tires between spring and fall races on the same track, but vice president of competition Robin Pemberton said it made sense at repaved Kansas Speedway. Jimmie Johnson was the fastest of 38 drivers who tested the new tires during a 3-hour session that was delayed by rain. … The race is the fourth in the 10-race Chase for the Championship.
