NASCAR Xfinity Series, Race No. 14 – American Ethanol E15 250

NASCAR Camping World Truck Series, Race No. 9 – M&Ms 200

Teams in both the NASCAR Xfinity and Camping World Truck Series teams will run the same tire set-up at Iowa this weekend. The same combination of left- and right-side tires these teams ran at Iowa last season. the left-side tire code (D-4546) has been run by Xfinity and Truck teams at Iowa since 2012, while this right-side tire code (D-4648) was introduced at the track in 2015. This is the only track at which teams in either of these two series are scheduled to run these tire codes in 2017.

As on most NASCAR ovals one mile or less in length, teams will not run inner liners in their tires at Iowa.
