Yokohama Introduces Two New Radial OTR Tires

Yokohama Tire Corporation unveiled two new off-the-road (OTR) radial tires at CONEXPO-CON/AGG, held March 4-8 in Las Vegas, Nevada.

“The new RL45 and RL51 spotlight our latest technology in OTR radial tire tread design,” said Tim Easter, Yokohama director, OTR sales. “Among the many benefits, the new treads are more durable and last longer.”

The RL45 E-4 is made for articulated dump trucks and scrapers and the L-4 version is for front-end loaders. “It’s the toughest radial for the most demanding applications,” said Mr. Easter. “Many manufacturers combine the L-4 and E-4 into a single application, but Yokohama built a tire for each, so there is no compromise for either application.”

The RL45 is available in size 26.5R25. It features an advanced tread composition which provides improved wear, low-heat generation and cut-resistance while the zigzag-shaped groove provides better traction on rock and gravel surfaces. Its non-directional block pattern provides abrasion- and cut-resistance on stone and gravel surfaces.

The RL51 L-5 application is designed for front-end loaders and graders. Available in size 23.5R25, the RL51 also features a non-directional block pattern which offers traction and stability – same performance in forward and reverse – as well as abrasion- and cut-resistance on rock and gravel surfaces.

Also on display at CONEXPO-CON/AGG were the RT41™ E-4 with a new CPUG (cut protective underground) tread compound for articulated dump trucks and scrapers.

“The CPUG compound was specially developed for underground usage. It helps increase the life of the tire and offers protection from cuts, punctures and wear,” said Mr. Easter.

The RT41 CPUG is constructed with four steel belts to resist punctures and add stability, and features buttress side protection, which prevents sidewall damage. It is available in three sizes: 23.5R25, 26.5R25 and 29.5R25.
