Description
The Firestone Sport 245/40 R20 is engineered for premium passenger sedans and sport crossovers (such as the Mercedes S-Class, BMW 7 Series, Audi A6/A7, Lexus LS, and sport trims of the Hyundai Tucson with 20-inch wheels). Developed with Bridgestone Group technology, this tire operates efficiently under high thermal stress, providing robust stability and excellent handling on dry and wet highways.
Key Product Advantages:
Balanced Stability & Braking Traction: The 245 mm section width coupled with a 40-series profile provides an optimized contact patch, ensuring chassis stability during lane transitions and reducing emergency stopping distances.
