Teams in all three NASCAR series will run the same Goodyear tire
codes this week. This combination of left- and right-side tires is
different than what was run at Kentucky last season bringing the tire set-up
in line with what is run at other speedways to enhance grip.
In Xfinity and Camping World Truck, the compounds remain the same on both sides of the car, there are construction and mold shape changes on the left-side and
just a construction change on the right-side. The Xfinity and
Truck changes also bring this tire set-up into line with what is run at
similar tracks and will give the cars/trucks more grip.
Teams are very familiar with this left-side tire code, having run it at Texas,
Dover and Chicagoland (Xfinity only) already this season, as well as
many other times over the past several seasons.
This tire set-up came out of a Goodyear test at Kentucky on April 13-14. As on all
NASCAR ovals greater than one mile in length, teams are required to run inner liners
in all four tire positions at Kentucky while air pressure in those inner liners should be
12-25 psi greater than that of the outer tire.
