Yokohama Tire Corporation has added four new sizes to its 104ZR all-position/steer tire lineup designed for urban and regional applications.

The new sizes added to the 104ZR line include 225/70R19.5, 245/70R19.5, 265/70R19.5 and 285/70R19.5. The tire is still available in its original sizes as well: 295/80R22.5, 9R22.5, 10R22.5, 11R22.5 12R22.5 and 315/80R22.5.

“The 104ZR is a true workhorse that’s designed to deliver longer treadwear, low rolling resistance and even wear, making it especially ideal for high scrub applications,” said Tom Clauer, Yokohama Tire manager of commercial and OTR product planning.

The 104ZR features a five-rib, full-depth tread pattern that is designed to deliver a smooth and quiet ride. A serpentine groove pattern reduces premature shoulder step-down and irregular wear to preserve overall tread life.

The tire also uses Yokohama’s Zenvironment technology which predicts casing growth and helps with stabilized performance over the life of the tire, longer casing life and improved retreadability. The 104ZR is made of specialized compounds which are strong and pliable, improving treadwear and low-rolling resistance.

Block-shaped stone defense ribs prevent stones from traveling to the bottom of the grooves, reducing casing damage by up to 25% to improve durability and retreadability. Also, an ultra-wide top steel belt increases rigidity across the entire tread surface to improve durability and avoid casing damage.
