For drivers who own sports cars or higher performing sedans and are looking for a tire that not only handles all
types of weather conditions, but also allows for more spirited driving, the Kumho Ecsta 4X KU22 could be just what
you're looking for.
The asymmetric tread design on the Ecsta 4X uses Kumho's advanced silica tread compound. This compound, combined
with the intermediate tread blocks and larger shoulder blocks on the outside of the tire, is built to provide high
performance handling and increased steering response in the corners.
A notched center rib around the tire adds more stability for straight line acceleration. It also helps to reduce
outside road noise.
Wet surface traction is enhanced through four circumferential grooves and added lateral grooves. Driving on snow
covered roads is made safer due to the multiple sipes around the tread that provide numerous biting edges resulting
in better handling.
Kumho uses ESCOT, or tension control optimization, technology for the carcass of the 4X, which gives the
sidewalls and shoulders of the tire better uniformity and distributes the pressure more evenly. This helps keep the
tire cooler, and adds durability as well.
Inside the tread you will also find two belts made of high-tensile steel and a spirally wrapped jointless cap
ply, which work together to give the tire more durability and stability at higher speeds.
All-season tread design provides good traction in winter weather conditions
6-year or 40,000 warranty is very good for tires in this class
Would like to see a touch better wet pavement traction
The Ecsta 4X ranks as one of the better performing high-performance all-season tires. While we feel models like
the Bridgestone RE970AS, among others, are at the top of the class, this Kumho model is impressive. Dry surface
traction and steering response are excellent.
The ride is very comfortable and road noise is minimal. While wet traction and handling are above average in its
class, it could be improved on to take over the number one slot. Overall, a very nice tire from Kumho.
Kumho warrants the Ecsta 4X for 6-years or 40,000 miles. A 1-year or first 2/32 inch of wear guarantee is
provided for tire uniformity.
Materials and workmanship are backed for 6-years and include free replacement during the first year or first
2/32 inch of wear. The amount is prorated for the remaining time period or until the final 2/32 inch of tread
You will also receive a first 2/32 inch of wear road hazard warranty on this model as well.
