Kumho Ecsta 4XII Tire Review & Rating

The new Kumho Ecsta 4X II is built to replace the original Ecsta 4X (KU22) in the company’s ultra-high performance tire lineup. Designed for all types of sports cars, coupes and sedans, this second-generation model is built to increase year-round traction and deliver a longer lasting treadlife at a lower price than many other tires in the UHP all-season class.

The Ecsta 4XII features a new polymer blended tread compound that is created to enhance grip on all types of pavement and weather conditions. Kumho has also concentrated on winter weather traction by adding silica and other new resins that add noticeable improvement in this area.

Kumho Ecsta 4X II Tire Review

An symmetric tread pattern and larger shoulder blocks give the 4X II increased handling and cornering grip. You’ll notice the steering is quicker and more responsive than on the older version due in part to the tire’s optimized contact patch, continuous center rib and stiffer tread block design.

The addition of noise-canceling technology in the tread helps to reduce unwanted road noise and increase the overall ride comfort. It works well on this tire as you’l find there isn’t much in the way of excessive noise on most all road surfaces.

Inside the tire are dual high-tensile steel belts that are reinforced with spirally wrapped nylon for added strength and durability. The Ecsta 4X II comes in a variety of V and W speed rated sizes, and a 40,000 mile tread warranty is also included.

Pros

  • Very good dry and wet traction
  • Cornering grip and stability
  • Quiet and smooth ride
  • Treadlife looks to be increased

Cons

  • Traction in deep snow and braking on ice

Overall Thoughts

Kumho has really come up with a winning tire with their new 4X II. We liked the older version for the solid performance and lower price, and this newly updated model has only furthered the performance levels.

One of the few issues with the original tire was its treadwear. Kumho has addressed this with their new compound, which carries a 420 UTQG rating, and initial results look to be very good. What you’ll find on this updated version is that traction and handling are noticeably higher, while the ride is more quiet and smooth than it was on the previous tire. The only area we would like to see improved on would be traction on snow and ice, but it’s really no worse than what you find on most other tires in this class.

Kumho has stated that the main competition for their new 4X II will be the Continental ExtremeContact DWS, Michelin Pilot Sport A/S3 and a few other top models in the ultra-high performance class. While that may be a stretch for this tire we can safely say that for the much lower cost, the new 4X II delivers substantial performance for the buck and is a nice addition in this category.
