NASCAR Sprint Cup teams will have a new tire at Charlotte Motor Speedway.
The new right-side tire is a multi-zone tread tire that incorporates two distinct compounds on the same tire - one for endurance and heat resistance on the inner two inches of the tread and one for traction on the outer 10 inches.
The inner section features the same compound that was run on the same zone at Texas Motor Speedway earlier this year. The outer zone feature the compound run at Charlotte last year.
The tire setup was first tested in December at Charlotte with Carl Edwards, Dale Earnhardt Jr. Paul Menard and Sam Hornish Jr.
The tire setup was confirmed in a March 10 test at Charlotte with Aric Almirola, Kasey Kahne, Martin Truex Jr. and JJ Yeley.
Teams competing in the Sprint All-Star race will have 11 sets for the weekend. Teams in the Sprint Showdown will have seven sets for the weekend and receive four more if they advance to the All-Star race.
Teams have run the same left side compound at Charlotte since 2012.
Camping World Truck teams, who race Friday night at Charlotte, will use the same tires as the Cup teams. Truck teams are allowed seven sets for the weekend.
Throughout the two race weekends at Charlotte, Goodyear’s tires will be branded “Support Our Troops’’ as part of the Goodyear Gives Back program.
The Xfinity Series is racing at Iowa this weekend and also will have a new right-side tire there.
The new right-side tire features a construction change for better wear compared to what was run last year. The left side tire has been run there since 2013.
The tire setup was confirmed in a May 5 test with Ryan Blaney and Daniel Suarez.
Xfinity teams will be permitted six sets for the weekend.
This also is the same tire setup Camping World Truck Series teams will run at Iowa in June.
