Kumho Ecsta SPT XRP

The Ecsta SPT XRP (KU31) is Kumho's Ultra High Performance Summer self-supporting run flat tire developed to provide temporary, continuing mobility (up to 50 miles at up to 50 mph) in the event of a puncture causing air loss for sports cars, coupes and sedans. The Ecsta SPT XRP (Extended Runflat Performance) is 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 XRP tires are not intended to be driven in near-freezing temperatures, through snow or on ice. Ecsta SPT XRP 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 XRP to let drivers know the time has come to rotate tires to maintain more even wear and lower noise levels as the tire approaches the later stages of its treadlife. The Ecsta SPT XRP tire's structure includes twin steel belts reinforced by a spiral-wrapped, jointless, nylon cap ply to enhance ride quality while providing high-speed durability. Rubber run flat inserts are molded on the inside of both of the tire's sidewalls to provide temporary continuing mobility in the event of a puncture causing air loss.
