The Pattern
Ventus S1 evo4 X K137A

Ultra-high-performance summer tyre engineered specifically for larger SUVs and crossovers.

The Ventus S1 evo4 X (K137A) is the SUV-specific version of Hankook's fourth-generation Ventus evo range. It carries a reinforced construction tuned to the higher weight and centre of gravity of larger SUVs and crossovers, helping it stay stable and composed at speed and through corners. The compound is developed to balance confident dry and wet grip with lower rolling resistance and longer tread life, making it a practical choice for drivers who want sporty handling without sacrificing everyday running costs.

  • SUV-specific reinforced construction for stability under higher vehicle weight
  • Fourth-generation compound tuned for dry and wet grip
  • Designed for lower rolling resistance to help fuel economy
  • Longer tread life than the previous evo generation
  • Available in large-diameter fitments for premium SUVs
Best for Performance SUVs and crossovers on everyday and faster road use
