Sprint Cup and Xfinity Series teams will be competing on different tire setups this weekend at Charlotte Motor Speedway.

Sprint Cup will be using the same tires they had for the Coke 600 and the All-Star Race back May.

Teams will be allowed five sets of tires for practice and qualifying and 10 sets for the Bank of America 500.

Xfinity teams will be allowed eight sets of tires for the entire race weekend.

This is the same tire combination the series used in Charlotte in May.

This right-side tire code employs Goodyear’s multi-zone tread technology, which combines two distinct tread compounds on the same tire — the outboard 10 inches of the tread (Traction Zone) features a compound that is designed for grip, while the inboard two inches of the tread (Endurance Zone) is toughened to enhance durability on the part of the tire that sees the most heat and takes the most abuse. As on all NASCAR ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Charlotte. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
