Fronway Speedway 56 – 255/35ZRF19 96W XL Run-Flat

Description: The Fronway Speedway 56 in 255/35ZRF19 96W XL Run-Flat is an Ultra High-Performance (UHP) tyre designed to provide premium safety and handling without the premium price tag. Engineered with self-supporting run-flat technology, this tyre is a direct replacement for original equipment on many executive saloons and sports coupes, such as the BMW 3 Series and 4 Series, Audi A5, and Mercedes-Benz C-Class. It combines peace-of-mind safety features with an asymmetric tread pattern optimized for cornering stability and wet-weather control.

Key Features and Technical Details:

• Run-Flat Technology (RFT): The standout feature of this tyre is its reinforced self-supporting sidewalls. In the event of a puncture or sudden loss of air pressure, the tyre structure is designed to hold the vehicle’s weight, allowing you to drive for a limited distance (typically up to 50 miles / 80 km) at a reduced speed to reach a service station safely.

• High-Speed Performance: Rated W (up to 168 mph / 270 km/h), the Speedway 56 is built for high-speed stability. The ‘ZRF’ designation confirms it is a radial run-flat tyre engineered for performance applications, ensuring the tyre maintains its shape and grip under high thermal stress.

• Extra Load (XL) Capacity: With a load index of 96, this reinforced tyre can support up to 710kg (1565 lbs) per tyre. This high load capacity is crucial for maintaining the handling dynamics of heavier modern vehicles equipped with run-flat systems.

• Asymmetric Tread Design: The tread features a dual-zone pattern. The continuous solid centre rib enhances straight-line stability and steering response, while the rigid outer shoulder blocks provide maximum grip during aggressive cornering.

• Wet Weather Safety: Four wide longitudinal grooves are strategically placed to rapidly evacuate water from the contact patch. This efficient drainage system significantly reduces the risk of hydroplaning and improves braking performance on wet roads.

• Comfort-Optimized Pitch: Despite the stiffer sidewalls inherent to run-flat tyres, the Speedway 56 utilizes a variable pitch tread block sequence. This design breaks up airflow to reduce road harmonics, contributing to a quieter and more comfortable cabin environment.
