Kumho Ecsta PS71

The summer tire Kumho Ecsta PS71 is one of the novelties of the South Korean brand. Like other models in this line, it is designed for passenger cars, namely their most dynamic versions, since it belongs to the UHP category. The development was carried out from "scratch", so the tire externally does not resemble the previous model with the index KU39, surpassing it in most characteristics, including braking distance and coupling on a wet surface.

Improved compound

To a greater extent, the advantage in terms of coupling properties on a wet surface is provided by the physical and chemical properties of the rubber mixture. Its composition includes a number of high-tech materials of the new generation: butadiene-styrene rubber and special polymers, which made it possible to increase the silica content. As a result, the tread literally sticks to the road surface, ignoring its low temperature in the rain.

New tread design

Another innovation was the tread pattern. Like the previous model, it has an asymmetric directional design, but at the same time provides the tire with much more performance. Especially on a wet surface. It contains an increased number of drainage grooves, the volume of which has become larger. They are arranged in such a way as to maximize the acceleration of the contact patch drying process.

Main features of Kumho Ecsta PS71

- designed specifically for sports versions of passenger cars;
- improved compound with high-tech materials of the new generation and increased silica content;
- large contact patch sizes provide excellent coupling with dry surfaces;
- optimized arrangement and significant number of drainage grooves minimize the risk of aquaplaning at any speed.
