Fronway Speedway 56 – 205/45ZRF17 88W XL Run-Flat

Description: The Fronway Speedway 56 in 205/45ZRF17 88W XL Run-Flat is an Ultra High-Performance (UHP) tyre specifically designed for compact performance cars, hot hatchbacks, and small sports coupes that require the added safety of run-flat technology. This size is a common fitment for vehicles like the MINI Cooper S, certain BMW 1-Series models, and high-spec Volkswagen Polo or Golf variants. It provides a sporty handling feel, reliable wet and dry grip, and the critical benefit of extended mobility after a tyre pressure loss.

Key Features and Technical Details:

• Run-Flat Technology (RFT): The defining feature is the self-supporting sidewall structure, which is heavily reinforced. This allows the tyre to maintain its structural shape and support the vehicle’s weight following a complete air pressure loss, 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 88 load index means this tyre is certified to support a maximum load of 560kg (1235 lbs) per tyre. The XL (Extra Load) designation indicates a reinforced construction that is vital for handling the dynamic forces and stiffer suspension setups often associated with performance compact vehicles and run-flat tyres.

• High-Speed Stability: Rated W (up to 168 mph / 270 km/h), the Speedway 56 is certified for demanding, high-speed applications. The ‘ZRF’ in the size code signifies a high-speed radial run-flat tyre, confirming its ability to maintain structural integrity and performance stability at speed.

• Asymmetric Tread Design: The high-performance asymmetric tread pattern features continuous center ribs for excellent straight-line stability and sharp steering response. The robust outer shoulder blocks maximize lateral grip, enhancing cornering performance for a sporty driving experience.

• Hydroplaning Resistance: The tread pattern incorporates multiple wide circumferential grooves that are designed for rapid and efficient water evacuation from the contact patch. This system significantly improves resistance to hydroplaning and ensures better braking and traction in wet conditions.

• Comfort-Focused Engineering: Despite the stiffer sidewalls inherent to run-flat designs, the Speedway 56 employs an optimized variable pitch tread block sequence. This technology helps to disrupt and minimize road noise harmonics, contributing to a quieter and more comfortable driving experience.
