Tire Description

The Ecsta ASX (ASX for All-Season Xtreme) (KU21) is a member of Kumho's race-proven Ecsta high performance tire family. It is an Ultra High Performance All-Season tire that was developed to meet the needs of the drivers of sports cars, coupes and sedans by blending responsive handling with dry, wet and year-round traction, even in light snow. On the outside, the Ecsta ASX molds a high technology silica and carbon tread compound into an asymmetric tread design that features large outside tread blocks for quick response and sporty handling with high volume circumferential and high angle slant grooves to resist hydroplaning and enhance wet traction. Constant contact center blocks help reduce noise while providing continuous road contact to improve straight-line stability. Internally, Ecsta ASX tires feature Kumho's Dynamic Casing Shape Technology that controls casing tension throughout the tire. This allows the Ecsta ASX to increase ride comfort by absorbing bumps and increase handling by remaining stable when cornering. Ecsta ASX tires feature twin, high-tensile steel belts with spiral-wrapped jointless cap and belt edge strips to stabilize the tread area enhancing handling, high-speed capability and ride quality while minimizing weight.

Customer Reviews

Awesome tires! I have been nothing but impressed! I like to drive in all types of environments. I have been all over the West Coast...in the desert, on the coast, and I am in Alaska right now. I figured, "For the price, I could just buy another set. I have been through 4 other sets of tires with my ride...Pirelli(OE) and Bridgestone. Neither one of those products even comes close to these!! These 'stop on a dime', are super-tight in the corners, ride 'smooth as silk', and I have been quite impressed with their performance on ice. We have varied conditions in Alaska...It could be 25F one day, and -20F the next. These tires have measured up. I have paid over $800 a set for my other sets. These were $419 shipped to ABQ, NM. How can someone go wrong. I will probably order another set this Summer. Two other things: I run these at 35PSI and I garage most of the time in the cold. The rubber in these tires stays totally pliable, even in the cold.
