Notes – New tire set-up for Xfinity, Truck teams at Iowa: Teams in both the NASCAR Xfinity and Gander Outdoors Truck Series will run the same tire set-up at Iowa this weekend . . . this is the first time teams in these two series have run this combination of left- and right-side tires at Iowa, though Xfinity teams did run this left-side tire code at Phoenix in March . . . compared to what was run at Iowa last season, both this left- and right-side tire feature minor construction changes to align them with what is run at similar tracks and compound changes for more grip . . . this tire set-up came out of a Goodyear test at Iowa on April 16-17 . . . drivers participating in that test were Christopher Bell, Cole Custer and Tyler Reddick . . . as on most NASCAR ovals one mile or less in length, teams will not run inner liners in their tires at Iowa.
