Tires are a major concern this weekend at Kentucky Speedway. Goodyear had a tire test and noticed some blistering happening within the tires, which resulted in the tire compound to be changed last minute. Goodyear has asked teams to scuff their tires. Because of this last minute change, NASCAR has given teams in all three series an extra set of tires.
For the Sprint Cup Series, the left side tires are the same ones used at Las Vegas Motor Speedway. The right side tires are a single tread version of the tires used at Michigan. Cup teams have six sets for practice and qualifying. Teams were given six sets of tires for practice and qualifying and 11 sets for the race.
For the Xfinity Series, the right side tires feature the multi-zone tread, similar to what was used at Las Vegas Motor Speedway in March. The left side tire used this weekend at Michigan is the same as the Sprint Cup. 10 sets of tires were given.
For the Camping World Truck Series, the left side tires are the same as Cup and Xfinity. The right side tires are the same as Xfinity. Teams were given 8 sets for the whole event.
Goodyear is awaiting teams to have long runs to see how the tires are holding up.
Carl Edwards in his media availability stated, “For us, we scuffed a bunch of tires. While we’re doing that, I’m looking at the little nuances of the track, where are the bumps, the grip level, exactly where is the speed. This track is difficult. Determining how you’re going to balance the car to be aggressive and how loose you need to be here or there, it’s kind of hard to figure it out, but that’s what I was working on.”
