The ECSTA SPT (KU31) is KUMHO's Ultra High Performance Summer tire developed for sports cars, coupes & sedans. The ECSTA SPT was designed to offer grip, handling, comfort, wear & 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 snow.

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 & three solid center ribs to combine wet grip, responsive handling & 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 & 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.
