Kumho Ecsta PS91
This model is a Performance Summer tire developed especially for owners of sports coupes, performance sedans for whom precise steering, responsive handling, and safety are the main priorities.
The Kumho Ecsta PS91 comes with an innovative summer tread compound molded into an asymmetrical tread pattern that presents a C-Cut 3D design that enhances block stiffness, for optimal braking and acceleration performance, maintaining high stability on the roads.
In the production of this model, the Kumho engineers use heat releasing dimple technology that maximizes thermo-diffusion and high-speed durability. Computer-optimized lateral groove angles manage irregular wear while maximizing water displacement during wet-weather cornering.
For safety reasons, it has three main and one secondary circumferential grooves designed to boost water evacuation from under the footprint for high hydroplaning resistance.
The Kumho Ecsta PS91 is available from 15 to 18-inch sizes, in Y-speed rating. It is a default option for sporty Porsche 911, Chevrolet Corvette, Mercedes E63 AMG, BMW M6, Audi RS7, and many other models.
