Hankook Ventus S1 evo2 K117B
Unlock quick steering and confident wet traction with the Hankook Ventus S1 evo2 K117B. This ultra high performance summer tire suits sport sedans and coupes that want precise response, strong braking, and a composed ride. Its asymmetric tread and reinforced construction steady the car at speed, while wide grooves move water to resist hydroplaning. Select sizes add run-flat capability for extra peace of mind, and you can choose the exact size, load index, and speed rating to match your OE specs.
Why choose the Ventus S1 evo2 K117B
The Ventus S1 evo2 K117B blends high speed stability with daily comfort. An asymmetric pattern delivers crisp turn in and predictable feedback, and a silica summer compound keeps the tire planted in warm weather. Wide circumferential channels and lateral grooves clear water for confident wet braking. Many drivers pick the K117B for its balance of grip and value, plus the availability of run-flat variants in key sizes.
Design and tread technology
A stiff outer shoulder and a continuous center rib boost on center feel and cornering stability. The asymmetric layout lets the inner zones sweep water while the outer blocks focus on dry grip. A silica rich compound promotes warm weather traction and helps reduce rolling resistance for efficiency. Variable pitch sequencing helps manage road noise, and on run-flat sizes, reinforced sidewalls support limited mobility after a loss of air when used as directed.
Real-world performance
In the dry, the K117B delivers direct steering and confident braking, so spirited drives feel precise and controlled. On wet roads, wide grooves and lateral channels shed standing water to cut hydroplaning and maintain grip. Despite its performance bent, the tire maintains a composed ride and keeps cabin noise in check. As with any summer tire, traction falls as temperatures near freezing, so switch to a winter tire when temps stay below about 45 F (7 C).
Sizes, fitment, and run-flat markings
Popular fitments include 18 and 19 inch sizes such as 225/50R18, 245/45R19, and 275/40R19 with performance focused load and speed ratings. Always match your door jamb label or owner's manual for size, load index, and speed rating, and confirm whether your vehicle was supplied with run-flat tires from the factory. Select K117B sizes include run-flat capability, typically marked RFT or with model specific codes on the sidewall. If your vehicle requires run-flats, do not mix run-flat and non run-flat tires on the same axle, and replace in axle pairs for consistent handling.
How to read sidewall codes: RFT, HRS, MOE
Run-flat versions usually show RFT on the sidewall, and some carry manufacturer specific codes. HRS is Hankook's run-flat system, and MOE signals a Mercedes oriented extended mobility spec. You may also see OE symbols for specific brands. These markings do not change the tire's size or speed rating, but they confirm limited mobility capability when used according to the maker's guidelines, so verify they match your vehicle's OE requirements.
Pricing, warranty, and value
The Ventus S1 evo2 K117B delivers strong performance per dollar. Price varies by size and spec, including run-flat options. Many UHP summer tires do not include a treadwear mileage warranty, coverage typically centers on materials and workmanship for a defined term. To maximize value, keep pressures at the vehicle spec, rotate regularly, and maintain alignment, then shop your exact size for current pricing and availability.
Ventus S1 evo2 K117B vs other UHP summer tires
Against premium UHP summer options from brands like Michelin, Bridgestone, or Pirelli, the Ventus S1 evo2 K117B stands out for everyday performance at a compelling price. Steering response and wet confidence are competitive for spirited street driving, while noise and ride comfort stay well controlled for a UHP tire. Top tier flagships may hold small gains in ultimate grip or braking, but many drivers will prefer the K117B's balance of performance, comfort, and value, especially when run-flat capability is required.
