The Pattern
Ventus S1 evo Z K129

A max-performance summer tyre built for sporty cars, with sharp steering and strong wet-weather grip.

The Ventus S1 evo Z K129 is a max-performance tyre developed for sporty coupes, hot hatches and performance saloons. Its silica-based compound, derived from racing tyre development, is designed to grip firmly at higher temperatures for confident handling and braking. An asymmetric tread with wide shoulder grooves clears water quickly, giving it strong resistance to aquaplaning, while a solid centre rib helps it stay stable and precise at speed. Independent tests praise its keen steering and short wet braking distances.

  • Silica-based compound developed from racing tyre technology for grip in warmer conditions
  • Asymmetric tread pattern for firm cornering and straight-line grip
  • Wide shoulder grooves that clear water and resist aquaplaning
  • Solid centre rib for stability and precise steering at speed
  • Fitted as original equipment on several high-performance models
Best for Sporty coupes, hot hatches and performance saloons
