Description
The Firestone Sport 255/40 R19 is designed for premium passenger sedans and sports cars (such as specific trims of the Mercedes E-Class, BMW 5 Series, Audi A6, and Ford Mustang). Developed with Bridgestone Group technology, this tire is engineered to operate efficiently in hot weather conditions, offering high heat dissipation and optimized wear resistance.
Key Product Advantages:
High Stability & Braking Traction: The 255 mm width provides an expanded contact patch with the asphalt, ensuring vehicle stability during lane changes and reducing emergency stopping distances on both wet and dry roads.
Reinforced Extra Load Casing (XL): Sidewalls are fortified with additional internal cord plies to withstand high inflation pressure and heavy loads, protecting premium 19-inch alloy wheels from deformation when hitting potholes.
Maximum Safe Speed Rating (Y): Technically certified to run with total safety and structural stability under high temperatures at continuous speeds up to 300 km/h.
