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.

Nothing to report – Perfect
Moderately good tyres
Very satisfied, highly recommended, happy to use again.
For now, nothing to say, impeccable. We'll see over time.
Superb quality, tyres run excellently. Super fast delivery, great prices. Always happy to return. Thank you.
Good feedback.. good grip both on dry and wet!! excellent value for money
Service was perfect. Delivery time is a bit long.
I am satisfied.
I have been using the tyres for about 2 weeks now on the Mercedes C 450 AMG. The tyres can easily keep up with the Continental Sport 5. The dry traction is even better than the Continental. I can't say anything about the wet performance yet, as I haven't tested them in those conditions. I can recommend the tyres for sporty cars.
Never received my order despite requests for tracking and other inquiries.
