The Yokohama 104ZR urban/regional all-position/steer tire is designed to deliver longer treadwear, low rolling resistance and even wear. A five-rib, full-depth tread pattern serves to provide an exceptionally smooth and quiet ride. Yokohama’s serpentine groove pattern is designed specifically to reduce premature shoulder step-down and irregular wear, further preserving overall tread life. The 104ZR also employs Yokohama’s Zenvironment technology, which accurately predicts casing growth and helps with stabilized performance over the life of the tire, longer casing life and better retreadability.
