With cooler temperatures again this spring, NASCAR's Cup Series drivers have quite the challenge ahead of them at Bristol Motor Speedway.
Practice quickly showcased noticeable cording and aggressive tire wear within 40 laps for most cars. Those battling tight conditions wore the right front down to nothing, while those battling loose conditions burned the left rear tire off. There seemed to be no escaping it, other than to back down the overall pace. Tire rubber was balling up at the top of the track as marbles and drivers did not want to come up off the bottom lane where the grippy PJ1 TrackBite was located (a synthetic resin that adds grip).
