This weekend both Cup and Xfinity teams race at Pocono Raceway, the three turn, 2.5-mile track in Long Pong, Pennsylvania.
Each series will have the same type of tires, including a new left-side tire code. Compared to what was run in 2017, this left-side tire features a construction update to align it with what is run at other speedways.
As on all NASCAR ovals greater than one mile in length, teams are required to run inner liners on all four tires. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
Here’s the tire info for Cup and Xfinity.
