The annual NASCAR Sprint Cup Series stop at Indianapolis Motor Speedway, which has had issues in the past with tire problems, will see some changes this weekend based on recommendations from Goodyear Tire & Rubber Co.
While teams in both NASCAR series in action at Indy will run the same right-side tire code (D-4476), they will be on distinct left-side codes. Cup teams have run this right-side tire at Indianapolis since 2012. Compared to last year, Cup teams will be on a different left-side tire code (D-4556), though they have run it at both Dover and Kentucky earlier this season.
Another change from last year is an increase in the minimum recommended air pressure in all four tires -- up four psi in the left-side tires and up five psi in the right-side tires. The recommended changes in set-up came out of a Goodyear test at The Brickyard on June 16 and 17.
