In September 1991, A. J. Foyt filmed a commercial for Craftsman tools at the Indianapolis Motor Speedway. While filming in the garage area, Foyt, and Speedway president Tony George decided to take Foyt's NASCAR Winston Cup car for a few laps around the track. Foyt was the first driver to do so, and later on, George himself took a few laps. The event was not planned, and had no implications, but caused some interest and speculation for the future.

On June 22–23, 1992, nine top NASCAR Winston Cup series teams were invited to Indy to participate in a Goodyear tire test. Over the weekend, the teams had raced in the Miller Genuine Draft 400 at Michigan International Speedway.

Although no official announcements were made, it was in fact an unofficial compatibility test to see if stock cars would be competitive at the circuit. An estimated 10,000 spectators watched two days of history in the making. A. J. Foyt took a few laps around the track in Dale Earnhardt's car on the second day.
