NASCAR Xfinity Series – Race No. 21 – Mid-Ohio Challenge

Notes: NASCAR Xfinity Series teams will run the same tire code (D-4590) on all four corners of the car at Mid-Ohio, the same tire Xfinity teams have run at this course for the last two seasons.
They are also scheduled to run this tire code again at Road America in two weeks. As on all NASCAR road courses, teams will not run inner liners in their tires at Mid-Ohio.
Wet Weather Tires: Goodyear will also bring its wet weather radials (D-4215) to Mid-Ohio for use by Xfinity Series teams, should NASCAR decide that conditions warrant.
