An ultra high performer for all seasons, Kumho Tire's Ecsta ASX KU21 combines outstanding wet and dry grip with high performance handling and competent snow traction – all while delivering long mileage and great ride comfort. The asymmetrical tread design optimizes all-season performance. High-tech silica compound delivers the optimum balance of wet and snow traction, treadwear and fuel efficiency. Large outside blocks maximize cornering performance. High-angle slant and circumferential grooves provide optimum water drainage to resist hydroplaning. E-technology step grooves and sipes increase edge effect for increased wet and snow performance. Multi-zone tread contour provides dynamic casing control for improved comfort and handling. The ASX’s ESCOT technology controls the tension throughout the casing to provide a comfortable ride and maintain performance handling. The jointless cap and edge covers keep the two full-width steel belts in place to ensure strength, stability and maximum footprint during high performance driving. Variable pitch tread blocks and cross-grooves reduce road harmonics for a quiet ride. Rim protector in lower sidewall safeguards wheel from scratches and abrasions. The Ecsta ASX comes with a 30,000-mile limited treadwear warranty.
