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
All-season tread design provides good traction in winter weather
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 depth.
You will also receive a first 2/32 inch of wear road hazard warranty on this model
