Fronway Speedway 56 – 235/55RF17 99V Run-Flat

Description: The Fronway Speedway 56 in 235/55RF17 99V Run-Flat is a Performance All-Season tyre specifically designed for mid-sized luxury sedans, family cars, and compact SUVs that utilize 17-inch wheels. This size is a common fitment for vehicles like the Audi A4, BMW 3 Series, and various crossover models, where drivers require a comfortable ride, stable handling, and the essential safety assurance of run-flat technology. It is engineered to deliver reliable traction across a range of dry, wet, and mild weather conditions.

Key Features and Technical Details:

• Run-Flat Technology (RFT): The defining safety feature is the heavily reinforced, self-supporting sidewall structure. In the event of a tyre puncture and subsequent total air pressure loss, this robust construction prevents the tyre from collapsing, enabling the driver to continue their journey safely for a limited distance (typically up to 50 miles / 80 km) at a reduced speed. The ‘RF’ in the size code denotes the Run-Flat construction.

• High Load Capacity: The 99 load index certifies this tyre to support a maximum load of 775kg (1709 lbs) per tyre. This robust load rating is crucial for safely managing the curb weight and suspension dynamics of modern executive and family vehicles.

• Performance V-Rating: Rated V (up to 149 mph / 240 km/h), this tyre provides ample speed capability for sustained highway driving. This rating confirms the tyre’s stability and structural integrity under load and at higher speeds.

• Asymmetric Tread Design: The tyre utilizes an asymmetric tread pattern optimized for versatile, all-season performance. The continuous center ribs ensure stable straight-line tracking and responsive steering, while the outer shoulder blocks enhance lateral grip and cornering confidence. The ample grooving is tailored for effective water evacuation.

• Wet Weather Control: Wide circumferential grooves and strategic lateral channels are integrated across the tread. This efficient drainage system works to rapidly channel water away from the contact patch, significantly enhancing resistance to hydroplaning and improving braking in wet conditions.

• Comfort Focus: The 55-series aspect ratio provides a good balance between stability and ride comfort. The tread pitch sequence is optimized to minimize air-pumping noise and road harmonics, contributing to a quieter and more pleasant driving experience.
