The heavy-duty tyre for the steering axle, the SmartFlex AH51 from Hankook, guarantees durability and performance for regional journeys. Designed to reduce fuel consumption while maintaining a high level of safety, it stands out with its innovative tread. This incorporates lateral longitudinal grooves with small step-shaped blocks, promoting even wear and the ejection of stones and debris (Equalized Stepper T.W.E.S.). The two central ribs are equipped with 3D micro-sipes, offering better flexibility and traction thanks to solidly interlocked blocks. Additionally, the SCCT (Stiffness Control Contour Theory) technology allows the tyre to support heavy loads by ensuring balanced weight and pressure distribution.
