BFGoodrich g-Force Rival S Updated compound for quicker warm-up in autocross competition. Enhanced “S”: compound offers maximum dry performance, sacrificing some wear, while still exceeding UTQG 200 standards. FASTER THAN THE LEADING COMPETITORS* – turn lower lap times at the track* and turn heads on the street. Extreme Tread Edge (ETE) design brings tread compound farther down the shoulder for increased grip in hard cornering and predictable feedback. DRIVE AT THE NEXT LEVEL – with an extreme grip that’s highly predictable, it’s like getting a talent upgrade. Performance Racing Core (PRC) – reinforced internal structure reduces sidewall flex for instant steering response.
