Kumho Ecsta PS91

Kumho ECSTA PS91 is an ultra-high-performance tyre developed for high-performance and sports cars, as well as drivers who prioritise responsive handling and confident road control. Its directional tread pattern features wide longitudinal grooves that help evacuate water from the contact patch, supporting wet-road traction while maintaining high-speed stability. The tread uses rigid blocks and a broad contact area to limit tread movement and support precise steering response, cornering control and braking performance during spirited driving. A high-grip compound is engineered to maintain strong road contact under demanding conditions, while the tread design balances dry-road performance with wet-weather capability. The ECSTA PS91 is therefore suited to drivers who want a performance-focused tyre for highway driving, fast road use and winding routes where steering precision and stability matter. Overall, it provides a responsive and controlled driving experience with a strong emphasis on dry handling, wet grip and high-speed road stability.

Best for:

  • High-performance and sports cars
  • Highway and high-speed road driving
  • Enthusiastic driving on winding roads

Not intended for: Drivers primarily seeking maximum ride comfort, low road noise, touring performance or off-road capability.
