Kumho Ecsta ASX Tire Review & Rating

As an ultra-high performance all-season tire, the Kumho Ecsta ASX is designed to provide both performance and value for drivers of all types of sports cars and sedans.

ASX stands for All-Season Xtreme, and Kumho uses the latest in tire technology, which includes a silica and carbon tread compound, to give this model better overall handling and response on both wet and dry surfaces. Cornering is also enhanced through the tires’ larger outside shoulder blocks.

Kumho Ecsta ASX Tire Review

The asymmetrical tread design sports slanted grooves and higher volume circumferential grooves to make it safer to drive on rain soaked road surfaces, and greatly reduce the possibility of hydroplaning as well.

Lower road noise and increased comfort is accomplished on the Kumho ASX through a more optimized tread block shape and better tension control in the casing. Another benefit to this casing technology is that pressure is more evenly distributed, which gives the tire longer and more even treadwear.

Inside the tread you will find two belts made of high tensile steel that are spirally wrapped. This gives the tire increased strength and handling at higher speeds. It also improves the overall ride quality on the tires. Kumho offers 16-22 inch sizes in the ASX, and it comes backed with a 30K mile tread warranty.


  • Very good dry pavement cornering and handling
  • Steering response is good
  • Tire rides well and there’s not a lot of road noise
  • Excellent value for the money


  • Tread life could be better
  • Wet traction

Overall Thoughts

The Kumho ASX offers reliable performance and control on dry surfaces. The steering is quick and responsive, and stability is quite good at higher speeds. Perhaps best of all it features a lower price point for those on a tighter budget who still want a very high level of performance in a tire.

Naturally, this tire is not without its faults. The biggest drawback with this model is its shorter treadlife. We’ve heard from drivers speaking of getting 25K miles out of the tread. Sure, if you’re hard on the tires you can expect to see a shorter lifespan, but we feel that treadwear is a bit short. The other issue is traction on wet pavement. We’d like to see a bump in wet grip, especially when cornering.

Overall, despite its negatives we still like this tire for its solid dry road performance and handling. It fills a much needed niche market in lower costing high-performance tires.
