NASCAR makes its second trip of the year to ISM Raceway near Phoenix this weekend.
All three national series will be in action for their final elimination playoff race.
All three series will run the same tire set-up on the 1-mile track.
Cup and Xfinity series teams will run the same right-side tire code they ran at Phoenix in March and a new left-side code (construction update).
Truck Series teams will be on a new tire set-up compared to their last race at Phoenix last year. Their left-side tire features a construction update, while the right-side tire features a compound change to introduce more wear and run cooler.
As on most NASCAR ovals 1 mile or less in length, teams will not run liners in their tires at Phoenix.
