The Kumho Ecsta PS91 is an Ultra High Performance summer tyre for sports cars and premium models, designed to deliver high stability at very high speeds.
It relies on a tread pattern designed to provide a fast steering response and enhanced grip. This design improves steering precision and traction, particularly during acceleration and changes in load.
With a (Y) speed rating, this tyre is suitable for speeds above 300 km/h. It targets stable road holding and strong endurance when driving conditions become extreme.
Its high-functionality rubber compound, combined with a reinforced structure, helps to maximise grip while ensuring durability compatible with the demands of sporty driving.
High-speed stability is supported by three-dimensional blocks and an advanced high-rigidity belt, in order to maintain consistent and safe handling under heavy loads.
The high-rigidity bead contributes to rim protection and lateral resistance, thanks to a more even distribution of stresses at the bead.
An integrated cooling system, based on micro-dimple technology designed to dissipate heat, promotes efficient thermal dispersion and contributes to the tyre’s longevity at high speed.
Optimising the internal and external structure of the tread helps to limit vibrations and road noise, improving comfort without reducing dynamic performance.
