The Xfinity and Sprint Cup Series will use the same tire setup this weekend at New Hampshire Motor Speedway as they return to action in the northeast.

A two-day tire test May 31 - June 1 resulted in a setup that will use the same left side tire that has run at New Hampshire since 2012. The right-side code, however, is new to the 1-mile oval.

Drivers who participated in the test were Aric Almirola, Dale Earnhardt Jr., Denny Hamlin, and Ricky Stenhouse Jr.


Set limits: Sprint Cup -- five sets for practice and qualifying and seven sets for the race; Xfinity -- six sets for the event

Tire Codes: Left-side -- D-4564; Right-side -- D-4706

Tire Circumference: Left-side -- 87.64 in. (2,226 mm); Right-side -- 88.15 in. (2,239 mm)

Minimum Recommended Inflation: Left Front -- 12 psi; Left Rear -- 12 psi; Right Front -- 30 psi; Right Rear -- 27 psi

Compared to what was run at New Hampshire last year, this right-side features a construction change to bring it into line with what is run at Phoenix and Richmond and a compound change to give cars more grip and introduce more wear over the course of a run.

As on most NASCAR ovals one mile or less in length, teams will not run inner liners in their tires at New Hampshire.
