Fronway Speedway 56 – 255/50RF19 103V Run-Flat

Description: The Fronway Speedway 56 in 255/50RF19 103V Run-Flat is a Performance All-Season tyre specifically designed for the large wheel fitments on modern luxury SUVs and crossovers. This size is a very common fitment for vehicles like the BMW X5, Audi Q7, and Mercedes-Benz GLE, where drivers require a blend of capable handling, comfortable highway performance, and the crucial safety assurance of run-flat technology. It delivers reliable traction across 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 total air pressure loss, this robust construction prevents the tyre from collapsing, enabling the driver to continue driving 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 103 load index certifies this tyre to support a substantial maximum load of 875kg (1929 lbs) per tyre. This high load rating is crucial for managing the significant weight and higher center of gravity characteristic of modern large SUVs and crossovers.

• 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 robust outer shoulder blocks enhance dry stability and cornering grip, while the inner tread elements are tailored for effective water evacuation and all-weather traction.

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

• Ride Comfort Focus: The 50-series aspect ratio provides a good balance between handling responsiveness and cushioning. The tread pitch sequence is optimized to minimize air-pumping noise and road harmonics, contributing to a quieter and more pleasant driving experience.
