Monster Energy NASCAR Cup Series, Race No. 12 – Coca-Cola 600
NASCAR Xfinity Series, Race No. 10 – Hisense 4K TV 300
Goodyear’s “Support Our Troops” Speedway Radials set-up for Charlotte features the same tread compounds as in 2016 in what is a well-suited combination for one of the most temperature-sensitive racetracks on the NASCAR circuit. These tires work well in a wide range of conditions, which is particularly important for the Cup cars in the Coca-Cola 600, which starts in the daylight and runs well into the evening. For NASCAR Xfinity Series teams, which are racing under a more reduced downforce package in 2017, they will get a grip improvement on both sides of the car with more tractive tread compounds compared to last year.
Teams in the Monster Energy NASCAR Cup Series and NASCAR Xfinity Series will run the same tire set-up at Charlotte this week that Cup teams used as their “Prime” tires during the All-Star event last week.
To honor American service members, all tires this weekend will be branded with “Support Our Troops,” instead of the customary “Eagle”, for the Cup cars, this is the same left-side tire code (D-4698) that teams ran at Charlotte last season, though this is a different right-side tire code (D-4732) compared to what was run in the points-paying races at Charlotte in 2016. The right-side tread compound is the same, but the tire features an updated construction to bring it into line with what is run at other speedways.
Xfinity teams, have a completely new tire set-up for Charlotte, in addition to the same right-side construction update the Cup cars received, this tire set-up features compound changes to both sides of the car for more grip. This tire set-up was run by Xfinity teams at a NASCAR organizational test at Charlotte on May 2.
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.
