NASCAR Xfinity Series, Race No. 23, Johnsonville 180

NASCAR Xfinity Series teams will run the same tire code (D-4590) on all four corners of the car at Road America, the same tire Xfinity teams have run at Road America since 2013. Teams also ran this tire code at Mid-Ohio road course two weeks ago.
As on all NASCAR road courses, teams will not run inner liners in their tires at Road America.
 
Wet Weather Tires: Goodyear will also bring its wet weather radials (D-4215) to Road America for use by Xfinity Series teams, should NASCAR decide that conditions warrant, the last time these teams ran it in competition was at Mid-Ohio last season.
