(INDIANAPOLIS) - A two-day NASCAR tire testing session ends today at the Indianapolis Motor Speedway.
Driver Kyle Petty is involved in the one-car testing session. Goodyear is hoping to gain data that will help when a 14-car testing session comes to the track in October.
The Allstate 400 at the Brickyard in July was marred by faulty tires that forced NASCAR to use competition caution periods nearly every 10 laps.
