Description
The Firestone Firehawk Sport 245/45 R20 is engineered for high-performance luxury sedans, modern crossovers, and sport-tuned SUVs (such as the Genesis GV70/G80, Lexus RX/NX, BMW X3/X4, Mercedes-Benz GLC, and top trims of the Toyota RAV4). This performance tire focuses on providing an optimized contact footprint and high lateral stiffness to deliver uncompromising stability under heavy acceleration and emergency braking on high-temperature summer tarmac, all while maintaining high structural safety.
