Storyline – Cup teams have a lot of experience on Gateway tire set-up: As the NASCAR Cup Series traverses the country visiting different race tracks, consistency in the Goodyear tire set-ups helps teams tune their car set-ups in varying conditions. The tire combination teams will run at World Wide Technology Raceway is a popular one, having been run in six races at four tracks in 2022, including at the suburban St. Louis facility. Cup teams have also already run this set-up three times in 2023 – at Phoenix Raceway, Richmond Raceway and North Wilkesboro Speedway.
“The tire set-up we’ll run at Gateway this weekend is one of the more tried-and-true in our tire lineup,” said Greg Stucker. “Since going to the 18-inch bead diameter tire at the beginning of last season, we’ve run this set-up at this group of tracks, including Gateway. The ability for teams to have that consistency in the tire is important to them being able to build a notebook and hone in on their car set-ups. Not only are they able to arrive at the track closer to where they want to be so they can take advantage of their practice time, they also know how the tire will react to other tuning tools.”
