Three Cup Series teams set for Goodyear tire test at Iowa Speedway

Three NASCAR Cup Series teams are set to participate in a two-day Goodyear tire test this week at Iowa Speedway. The routine test is scheduled for Tuesday and Wednesday as the 0.875-mile track prepares for a tripleheader weekend of racing Aug. 7-9, with the Cup Series sharing the card with the NASCAR O'Reilly Auto Parts Series and the ARCA Menards Series. The three-day set will be capped by the Cup Series' Iowa Corn 350 Powered by Ethanol on Sunday, Aug. 9 (3:30 p.m. ET, USA Network, HBO Max, MRN Radio, SiriusXM NASCAR Radio).

• Austin Dillon, No. 3 Richard Childress Racing Chevrolet
• Noah Gragson, No. 4 Front Row Motorsports Ford
• Tyler Reddick, No. 45 23XI Racing Toyota

Reddick, the Cup Series points leader and a five-time winner already this season, said Saturday at Watkins Glen International that he would shift from his primary focus on a busy May slate of races to Iowa testing upon arrival. "From my standpoint, I pretty much just wait till I get there to start figuring out what it's going to be like," Reddick said. "I don't really know what kind of lineup of tires they have or anything of that nature, but certainly I'll run the tires, give my feedback and hopefully they find a combination they like that continues to follow that trend of being softer and wearing out more and having more degradation." This summer's 350-lap event will be Iowa Speedway's third NASCAR premier series race. Ryan Blaney (2024) and William Byron (2025) are past winners.
