Exploding Goodyear puts Stewart in wall at Indy

Tony Stewart was running lap speeds more than a second faster in race trim than in the past when he blew a tire during a Goodyear tire test Tuesday at Indianapolis Motor Speedway.

The Stewart-Haas Racing driver was uninjured in the accident, which came 17 laps into a 20-lap run and was the only problem during the two-day test, according to Goodyear officials.

"Tony was approaching the end of a very strong 20-lap run, with his lap times as much as a second faster than what has become the norm at Indianapolis at that point of a run," Goodyear's Director of Racing Greg Stucker said in a statement. "It appears that increased, sustained speed over that run generated a significant amount of heat, which eventually caused the right-front to go down. Those are the conditions we have to consider in making the right decisions for the race."
