Michelin Tapped By Komatsu For Tires On Newest, Largest Haul Trucks

New Komatsu 860E standard on MICHELIN tires; 960E delivered on MICHELIN

September 22, 2008 LAS VEGAS -- MICHELIN® XDR™ earthmover tires are the standard fitment for the new Komatsu 860E-1K haul truck, introduced for the first time today at MINExpo. This state-of-the-art rigid dump truck is designed for the most demanding surface mine applications, and features a 280-ton capacity, 2,700-horsepower diesel electric-drive system designed by Komatsu. The truck is also designed with an optional factory-installed trolley option.

"The new Komatsu 860E will be expected to handle staggering workloads and requires a tire that can not only stand up under tremendous weight but also perform under the harshest conditions for a long time," said Luc Minguet, president of Michelin Earthmover and Industrial Tires. "Because of its durability and maximum wear life, the MICHELIN XDR tire is the ideal fitment for the new Komatsu truck."

Michelin also produces the only radial tires designed specifically for the Komatsu 960E-1 electric drive haul truck, which was introduced in May 2008. Michelin worked closely with Komatsu at their proving grounds in Arizona to test and confirm the MICHELIN XDR tire in the 56/80R63 dimension required for the 960E truck.

"Being the key tire manufacturer of the 63-inch dimension for the Komatsu 960E truck further demonstrates Michelin's leadership in the giant OTR tire industry," said Minguet.

The XDR tire features an extra-deep, rock-type pattern that delivers maximum protection in severe conditions, providing maximum wear life and minimum cost/hour. With tread up to 15 percent deeper than most ultra-class truck tires and thick, square shoulders, the XDR tire provides maximum protection in severe mining conditions. Deep, longitudinal grooves improve traction and, therefore, improve haul truck productivity. Unlike most haul truck tires, the XDR tire features independent blocks that run along the center of the tread line. These blocks come together as the tire rolls to spread the ground contact pressure evenly and minimize tread wear.
