Additionally, Goodyear held private tests at New Hampshire on July 8–10, with A. J. Foyt Enterprises (Scott Sharp and Davey Hamilton), Pagan Racing (Roberto Guerrero), Della Penna Motorsports (Richie Hearn) and Team Scandia (Eliseo Salazar), on which Hearn suffered a hard crash during the first day, although he was uninjured. During that month, Jonathan Byrd's Racing announced the end of their partnership with Treadway Racing to become partners with Cunningham Racing. Mike Groff, who had driven for Foyt and Walker Racing during the year, was selected as their driver, replacing Johnny O'Connell, who would remain on New Hampshire's entry list before being 'scratched'. Also, McCormack Motorsports announced the signing of an injury-free Stan Wattles, who was on the sidelines after Leigh Miller Racing's assets were bought by Beck Motorsports that spring.
