BFGoodrich g-Force R1 Tires for all types of vehicles

The g-Force R1 S (S for Sprint) radial is BFGoodrich's Racetrack & Autocross Only special-use DOT-legal racing tire developed for the drivers of prepared vehicles looking to run their quickest times in autocross, sprint race and time attack events. Offering more ultimate dry grip, g-Force R1 S tires come up to temperature quicker and provide more grip in cooler ambient temperatures on tracks that are easier on tires (compared to the standard g-Force R1). However, the g-Force R1 S will wear quicker than the standard g-Force R1 tires and are not as well suited for extremely hot days.
