This being the first ever NASCAR Camping World Truck Series race at Iowa Speedway, Goodyear conducted a tire test at the track on May 11-12 . . . Camping World Truck drivers that took part in that test were Colin Braun and Matt Crafton . . . also participating were NASCAR Nationwide Series drivers Justin Allgaier and Jason Leffler, in advance of their August 1 event at the speedway . . . Truck Series teams will be running the same combination of left- and right-side tires that Nationwide teams ran at Iowa last month . . . this is the only track at which these teams will use these two tire codes together, though they will run this left-side code (D-4178) at Gateway next weekend, and have run this right-side code (D-4160) at Bristol in 2008 . . . as on most NASCAR ovals one mile or less in length, teams will not run inner liners in their tires at Iowa.
