Yokohama Adds 49-Inch Construction, Mining Radial

The Yokohama Rubber Co. has released a large-size radial tire for rigid dump trucks in the construction and mining field – a 27.00R49 size model of its RB42.

The tire has a U.S. Tire and Rim Association code of E-4 and a two-star rating for tire strength, according to Yokohama, which added the lineup features "Regular" specifications for ordinary off-the-road surfaces, and "Cut Protected" specs with excellent cut resistance. This makes the tires suitable for a wide range of surfaces, from soft or loose surfaces such as mud or sand, to rough surfaces comprising gravel and rocks, the tiremaker added.

RB42 features a new belt structure for large-size radial tires and a specialized mold profile, as well as an exclusive tread compound that is newly developed for large-size radial tires.

“The global production of mineral resources is intensifying and with it, over the medium- and long-term, is increasing demand for large and ultra-large radial tires,” the tiremaker said. “In this circumstance, Yokohama intends to expand its presence in the mineral resources development sector through this official release of the large-size RB42.”

Ascot Supply Corporation, based in Newnan, Georgia, has selected Mark Paquette for the newly created position of vice president. In this position, Ascot Supply said Paquette will oversee the growth of the company's products, corporate profitability, manage marketing and advertising and assume many other responsibilities.

He will work under the direction of current President David Kessler and officially begin his new role on June 3. Paquette joined the tire and automotive industry in the early 1980s at his father's tire shop, and his contributions to Mohawk Rubber Sales were instrumental in the company's growth and eventual sale to Myers Tire Supply in 2021, according to Ascot Supply. Paquette eventually was given a promotion to the role of director of operations at Myers Tire Supply.
