Kumho Ecsta SPT KU31 Overview

The Kumho Ecsta SPT KU31 is an ultra high performance summer tire specially designed for drivers who are looking for good looks, superior grip, and comfort. Ideal for sports cars, coupes, and sedans, the Kumho Ecsta SPT KU31 will give you confidence to drive on dry roads even at high speeds.

These replaced a set of much more expensive Goodyear F1-GSD3 tyres which had to be replaced because of sidewall bulges at about 25 percent tread left. All I can say is that at only 70 percent the price of the Goodyears, these tyres provide at least 90 percent of the performance. And in some aspects, like steering sharpness and durability, outdid the more expensive tyre. Recommended without reservations.
