Teams in the NASCAR Sprint Cup Series will run a different tire set-up than those in Xfinity and Camping World Truck at Atlanta this weekend. This is the first time Sprint Cup teams have run either of these two tire codes, this right-side tire incorporates Goodyear Racing’s multi-zone tread technology, which debuted at Atlanta in 2013.
The tire features two distinct tread compounds — one for endurance and heat resistance on the inboard two inches of the tread and one for traction on the outboard 10 inches.
Compared to what was run at Atlanta last season, this right-side code (D-4682) features the same compound on the inboard, with a different compound for more grip on the outboard, this left-side code (D-4680) features changes to both compound (more grip) and construction (to bring in line with what is run at other speedways).
Goodyear held a tire test at Atlanta in early November 2015, teams participating in that test were Chip Ganassi Racing, Joe Gibbs Racing, Richard Childress Racing and Roush Fenway Racing.
As on all NASCAR ovals greater than one mile in length, teams are required to run liners in all four tire positions at Atlanta, air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
