Both the Xfinity and Gander Outdoors Truck Series will use a brand new tire setup for this weekend’s races at Iowa Speedway.

This is the first time teams in both series have used 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, the left- and right-side tires feature minor construction changes to align them with what is run at similar tracks and compound changes for more grip.

This tire setup is the result of a Goodyear test at Iowa on April 16-17 with Christopher Bell, Cole Custer and Tyler Reddick.

As on most NASCAR ovals 1 mile or less in length, teams will not run inner liners in their tires at Iowa.

Here is the tire info.
