Fronway Speedway 56 – 225/50ZRF18 95W Run-Flat

Description: The Fronway Speedway 56 in 225/50ZRF18 95W Run-Flat is a high-specification Grand Touring Performance tyre that incorporates essential run-flat safety technology. This size is a common fitment for luxury and executive vehicles, including models like the BMW 3 and 5 Series, Audi A4/A6, and Mercedes-Benz C and E-Class models, often used for vehicles prioritizing a balance of comfortable ride quality and capable handling. It is engineered to provide stable high-speed performance and reliable wet/dry traction, with the critical benefit of limited-distance mobility after a puncture.

Key Features and Technical Details:

• Run-Flat Technology (RFT): The defining safety feature is the heavily reinforced, self-supporting sidewall structure. This allows the tyre to maintain its functional 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.

• High Load Capacity: The 95 load index certifies this tyre to support a maximum load of 690kg (1521 lbs) per tyre. This robust load rating is crucial for managing the curb weight and suspension dynamics of modern luxury and executive-class vehicles, ensuring stability under load.

• 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 confirms a high-performance radial run-flat construction, optimized to resist heat build-up and maintain performance stability.

• Asymmetric Tread Design: The tyre utilizes an asymmetric tread pattern optimized for balanced performance. It features continuous center ribs for stable straight-line tracking and responsive steering, while the robust outer shoulder blocks enhance lateral grip and cornering confidence.

• Wet Weather Control: Multiple wide circumferential grooves and lateral siping details are integrated to effectively channel water away from the contact patch. This efficient drainage system enhances resistance to hydroplaning and ensures reliable braking performance in wet conditions.

• Comfort and Noise Reduction: The 50-series aspect ratio offers a balance between precise handling and ride comfort. Furthermore, the tread design employs an optimized variable pitch sequence to disrupt and minimize road noise harmonics, contributing to a quieter and more comfortable driving environment.
