Teams heading into Sunday’s Coca-Cola 600 at Charlotte Motor Speedway won’t be dealing with anything unfamiliar when it comes to tires, with Goodyear sticking to a package that’s already been heavily used this season. The same Racing Eagle combination has already been used at Las Vegas, Darlington, Kansas, and Texas earlier this year. All four of those races came on 1.5-mile intermediate tracks, which puts Charlotte in a direct line with what teams have already been working through this season.
This will be the fifth time Cup teams have run this setup in 2026, so they come into Charlotte with plenty of data already built. Teams know how the tire behaves over long runs, how the balance shifts as fuel burns off, and what kind of falloff to expect once the race settles into rhythm. That consistency has taken a lot of guesswork out of the equation, but it doesn’t make 600 miles any easier.
The package itself isn’t new anymore, but Charlotte still pushes it in a different direction. The left-side tire was first introduced in last year’s Coca-Cola 600, while the right-side tire has already been used earlier this season at Kansas, adding another layer of familiarity heading into the weekend. For O’Reilly Auto Parts Series and Craftsman Truck Series teams, the situation is slightly different.
They will run a new right-side tire paired with a left-side tire that has already been used at several 1.5-mile tracks this season. It’s close to what Cup teams are running, but not identical, and that difference usually shows up once long runs start to build and tire wear becomes a factor. Tire allotments remain limited across all three national series.
Cup teams will have 14 total sets for the weekend: 12 for the race, 1 for qualifying that transfers to the race, and 1 for practice. The O’Reilly Auto Parts Series will have 6 total sets, while the Truck Series will have 5. At Charlotte, every set carries weight. Teams are forced to balance early-weekend learning with saving enough tire life for a 600-mile race that often comes down to who can manage falloff best when it matters most.
Goodyear will also continue its Memorial Day weekend tradition for the eighth straight year, replacing its branding on all tires with the Honor and Remember logo as part of the weekend tribute. By Sunday night, most teams will already have a clear picture of what the tire will do. The real challenge won’t be figuring it out. It will be surviving it over one of the most demanding races on the calendar.
