Hankook VENTUS S1 EVO 2 K117 255/40R17 98Y

Hankook Ventus S1 evo2 K117 delivers ultra-high performance for drivers who demand precision and control. Its asymmetric tread and wide channels evacuate water quickly for confident wet grip and braking, while a high-grip silica compound and reinforced outer shoulder sharpen steering response and cornering stability. Optimised pitch sequencing lowers road noise for refined comfort, and a lightweight construction helps reduce rolling resistance for improved fuel efficiency. Ideal for performance cars and dynamic daily driving. Upgrade your tyre performance with Hankook today.

High grip silica compound. The Hankook Ventus S1 evo2 K117 employs a high-loading, high-dispersion silica compound with advanced silane coupling to raise wet friction coefficients without a proportional increase in hysteresis, cutting rolling resistance while shortening wet braking distances. The optimised Tg window and controlled filler–polymer interaction improve micro-scale adhesion on polished asphalt, while reduced filler–filler networking minimises energy loss under cyclic deformation. Precision mixing ensures uniform silica dispersion, delivering thermal stability and consistent grip under sustained high-speed loads on New Zealand roads.

Aqua driving control grooves. Four wide circumferential channels with angled lateral outlets generate high drainage capacity and maintain a stable pressure gradient across the contact patch, rapidly evacuating water to delay the onset of hydrodynamic lift. A multi-radius contour sustains a longer, squarer footprint in the wet, limiting water film thickness and preserving the tyre’s µ–slip curve during urgent braking. Chamfered groove edges reduce vortex formation, improving straight-line stability in heavy rain common on Kiwi highways.

Jointless full cover cap ply. A zero-degree, jointless nylon/aramid cap ply overlays wide, high-tensile steel belts to control carcass growth at speed, delivering low radial run-out and consistent contact pressure distribution. This construction raises the resonant frequency of the belt package, enhancing high-speed stability and steering precision while mitigating heat build-up during extended State Highway cruising. The result is confident, predictable handling from the Hankook Ventus S1 evo2 K117 at open-road speeds and beyond.

Rigid outer shoulder blocks. Large, reinforced outer shoulder blocks with 3D interlocking edges and connecting tie-bars raise lateral stiffness, boosting camber-thrust generation and linearising lateral force versus slip angle for crisp turn-in. The stiff shoulder resists tread squirm under peak lateral g, expanding the usable dry grip envelope and reducing outer-edge feathering on performance-oriented vehicles. Optimised block chamfers spread local contact stresses to curb heat spots during repeated cornering on coarse-chip New Zealand surfaces.

Visual alignment indicator bars. The Ventus S1 evo2 K117 integrates Hankook’s Visual Alignment Indicator wear markers on the shoulder ribs, enabling rapid diagnosis of toe or camber misalignment by comparing early-life wear of paired indicator bars within the first 1,000–1,500 km. Early detection allows prompt alignment correction, preventing irregular wear patterns such as heel-and-toe or one-shoulder scrub that elevate noise and diminish wet grip. This translates to longer, more uniform tread life and reduced total cost of ownership for your vehicle.
