Yokohama Tire Corp.’s latest regional-haul trailer tire, the 114R Ultra Wide-Base, is ready for sale, according to a Dec. 5 news release.

The SmartWay-verified 114R, the successor to RY407, is available in size 445/50R22.5, the company said. An additional size — 455/50/22.5 — will be offered in the first quarter of 2020.



“The 114R UWB is specifically designed to meet the demands of high-scrub operations,” said Tom Clauer, senior manager of commercial and OTR product planning. “It features superior cut and chip resistance, extended tread life and is optimized for fuel efficiency.”

Other benefits of the 114R include long-lasting performance, Yokohama said. The 16/32-inch groove depth provides extra-long tread life.

Yokohama said its zero-degree belt, a cornerstone to its durable and retreadable casing, creates a stable footprint for long, even wear.

The tire also has advanced compound, which offers cut and chip resistance without sacrificing rolling resistance or wear performance. Yokohama said its funnel-shaped step grooves prevent stones and other debris from reaching the bottom of the grooves, where casing damage often can occur. Ground

contact pressure is uniformly distributed, which results in greater stability, tracking and fuel efficiency.

Yokohama Tire is the North American manufacturing and marketing arm of Tokyo-based Yokohama Rubber Co., a global manufacturing and sales company since 1917.

Its product line includes tires for high-performance trucks, light trucks, passenger cars, commercial trucks and buses, and off-the-road mining and construction applications. — Transport Topics
