g-Force R1 S/R1S

The BFGoodrich g-Force R1 S/R1S is a superb DOT-legal racing and autocross tire designed to deliver extreme grip and speed on dry surfaces. Its size range ranges from 15 to 18-inches, molded at a 4/32-inch tread depth on a specialized compound. These tires' consistent gripping character and razor-sharp steering response are a force to be reckoned with in autocross competitions. They are also the ideal performance tire for high-speed enthusiasts. The BFGoodrich g-Force R1 S/R1S features a softer rubber that warms up quicker, ensuring a high-level performance in timed events like autocross.

 

The BFGoodrich g-Force R1 S/R1S stands out as a reliable, versatile, durable tire specially made to break lap times and win competitions worldwide. The structure of the BFGoodrich g-Force R1 S/R1S improved rubber allows for a better contact patch, while the tread pattern design leaves room for more improved cleavage and water draining, decreasing the risk of aquaplaning on wet surfaces. It incorporates a symmetric, semi-slick tread that makes the tire wearable on both sides of the vehicle to maximize its durability. The internal structure includes twin steel belts reinforced by a spirally-wrapped polyamide cord.
