FULLERTON, Calif. (Feb. 6, 2014) — Yokohama Tire Corp. (YTC) will unveil two radial OTR tires for articulated dump trucks/scrapers and front-end loaders at the ConExpo trade show at the Las Vegas Convention Center, March 4-8.
The RL45 and RL51 OTR radials are available in size 26.5R25 and 23.5R25, respectively, YTC said.
“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, Yokohama said, and the L-4 version is for front-end loaders.
“It's the toughest radial for the most demanding applications,” Mr. Easter said. “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 features:
- Advanced tread composition provides improved wear, low-heat generation and cut-resistance;
- Zigzag-shaped groove for better traction on rock and gravel surfaces;
- Non-directional block pattern provides abrasion- and cut-resistance on stone and gravel surfaces;
- High turn-up carcass construction protects against exterior damage with greater lateral stiffness;
- Buttress side protection helps against outside damage, resulting in fewer sidewall snags and cuts; and
- Flexible OTR belt wire creates a tough, multi-layer cross-ply steel belt package to improve durability.
The RL51 L-5 application is designed for front-end loaders and graders.
“This is a resilient radial for high-cut uses,” Mr. Easter said. “It has incredible traction and stability. It will not sway under load thanks to the advanced belt package.”
The RL51 also features:
- High-tech tread compound that provides better wear- and cut-resistance;
- Non-directional block pattern offers traction and stability as well as abrasion- and cut-resistance on rock and gravel surfaces;
- High turn-up carcass construction protects against exterior damage with greater lateral stiffness;
- Buttress side protection offers prevention against outside damage; and
- Improved durability heightened through an advanced, multi-layered cross-ply steel belt package.
YTC said it also will display at ConExpo its RT41 E-4 with a 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,” Mr. Easter said.
The RT41 CPUG is built 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.
