Fronway Speedway 56 – 245/35ZRF20 95W XL Run-Flat

Description: The Fronway Speedway 56 in 245/35ZRF20 95W XL Run-Flat is a highly specialized Ultra High-Performance (UHP) tyre that combines an extremely low profile with essential run-flat safety technology. This size is typically used on the front axles of high-end sports cars and luxury sedans with staggered 20-inch wheel setups, such as the BMW M5/M6, Audi RS models, and high-performance Mercedes-Benz models. It is engineered to deliver razor-sharp steering precision and maximum dry grip, all while providing the security of limited-distance mobility after a pressure loss.

Key Features and Technical Details:

• Run-Flat Technology (RFT): The tyre incorporates heavily reinforced, self-supporting sidewalls. This critical feature allows the tyre to maintain its structural shape and support the vehicle’s weight following a complete loss of air pressure, enabling the driver to continue driving safely for a limited distance (typically up to 50 miles / 80 km) at a reduced speed.

• Extra Load (XL) Capacity: The 95 load index certifies this tyre to support a maximum load of 690kg (1521 lbs) per tyre. The XL (Extra Load) designation indicates a robust internal construction necessary to handle the dynamic forces and increased unsprung weight of modern performance vehicles and their large-diameter wheels.

• High-Speed Stability: Rated W (up to 168 mph / 270 km/h), the Speedway 56 is built for sustained high-speed driving. The ‘ZRF’ in the size code confirms a high-performance radial run-flat construction, optimized to resist deformation and heat build-up inherent in low-profile, high-speed applications.

• Low-Profile Handling: The extremely low 35-series aspect ratio minimizes sidewall flex to an absolute minimum. This ensures instantaneous steering response, excellent lateral stability, and a direct, sporty feel, which is paramount for UHP driving.

• Asymmetric Tread Design: The high-performance asymmetric tread pattern utilizes a continuous center rib for precise straight-line tracking. The extra-stiff outer shoulder blocks maximize the contact patch during sharp cornering, contributing to superior dry grip and confident handling.

• Hydroplaning Resistance: Multiple wide circumferential grooves are integrated into the design to rapidly and effectively channel water away from the contact patch. This system works to improve braking performance and safety in wet conditions, crucial given the tyre’s wide, low-profile footprint.
