Director of Race Tire Engineering and Manufacturing. with Firestone Racing, Cara Krstolic said:
Barber Motorsports Park has a full schedule of racing events throughout the year across many categories of motorsports resulting in a racetrack surface that sees a lot of use and which naturally affects the track grip level over time. Taking that into account, Firestone has brought primary and alternate race tires with a combination of higher grip and higher rate of degradation designed to present more of a challenge and promote more competition.
