Tire Description

The Ecsta SPT (KU31) is Kumho's Ultra High Performance Summer tire developed for sports cars, coupes and sedans. The Ecsta SPT was designed to offer grip, handling, comfort, wear and good looks in order to provide enthusiastic drivers the ability to "Drive Hard 'Go Big' Look Good." Ecsta SPT tires are not intended to be driven in near-freezing temperatures, through snow or on ice. On the outside, Ecsta SPT tires feature Kumho's High Dispersion Silica tread compound (that broadens the tread rubber's temperature operating range) molded into a directional tread design that features large, independent shoulder blocks, four straight circumferential grooves and three solid center ribs to combine wet grip, responsive handling and high-speed stability. Rotation Wear Indicators (R.W.I.) are built into the Ecsta SPT to let drivers know the time has come to rotate tires to maintain more even wear and lower noise levels into the later stages of the tire's life. On the inside, Ecsta SPT tires feature twin steel belts reinforced by a spiral-wrapped, jointless nylon cap ply to enhance ride quality while providing high-speed durability.

Customer Reviews

I replaced the stock goodyear GS-C's which were total garabge. The GS-C's were much louder than the Cooper STT's on my truck. The Kumho's are truely awesome! Quiet, responsive and grip are great. I will put them on every sports car from here on out. On past sport/muscle cars I have ran Goodyear/Firestone and BFG radial T/A's. The Kumho's beat all of them hands down. I only drove once in the rain for about 5 blocks so I really can't speak for the wet performance. Every other aspect of the tires is awesome.
