The Kumho Ecsta PS91 is an Ultra High Performance summer tyre, designed for sports and premium vehicles requiring high stability at very high speeds.
Its design is based on a tread pattern that promotes immediate steering response and optimised grip. This architecture improves driving precision and traction, particularly during acceleration and changes of direction.
Rated (Y) for speed index, this tyre is suitable for speeds above 300 km/h. It delivers stable handling and high endurance in extreme driving conditions.
The high-functionality rubber compound, combined with a reinforced structure, helps to maximise grip while ensuring durability suited to the demands of sporty driving.
High-speed stability is enhanced by three-dimensional blocks and an advanced high-rigidity belt, helping to maintain consistent and safe behaviour under heavy loads.
The high-rigidity bead improves rim protection and lateral resistance, thanks to better distribution of stresses at the bead area.
An integrated cooling system, based on micro-dimple technology that dissipates heat, promotes efficient thermal dispersion and contributes to the tyre’s longevity at high speed.
Optimisation of the internal and external structure of the tread helps to reduce vibrations and road noise, improving comfort without compromising dynamic performance.
