See pages 50 - 51 for important product information. BFGOODRICH ® g-FORCE ™ R1 ™ & R1 ™ S UTQG = 40/B/A Available Sidewall = BSW LL = Light Load Important Note: The g-Force ™ R1 ™ and R1 ™ S tires are special-use products designed for competitive racing. As such, the following precautions must be observed when using these products. At the Racetrack: Never inflate the tire to less than 19 psi. Use the information provided in the BFGoodrich ® g-Force ™ R1 ™ Care & Feeding Brochure for cold inflation pressure guidelines and other product usage recommendations. On the Street: g-Force ™ R1 ™ and R1 ™ S tires have a reduced tread depth when new and a tread rubber compound optimized for maximum dry grip. As such, they will wear out much sooner and offer less wet grip when compared to normal passenger car tires. Therefore, observe tire-wear condition often. Do not use the tires on the street when the tread depth wears to less than 2/32-inch. Reduce speeds in wet conditions and whenever any standing water is present. The g-Force ™ R1 ™ and R1 ™ S are not intended for use in snow and ice conditions. Exceeding the safe, legal speed limit is neither recommended nor endorsed.
