New Michelin® Rigid Dump Tire Increases Productivity at Least 24 Percent

MICHELIN® XDR250 provides extra load capacity for 250-ton dumpers used in open pit mines  

GREENVILLE, S.C., July 1, 2015MICHELIN Earthmover today introduced a new mining tire for 250-ton rigid dump trucks that can increase hauling productivity at least 24 percent (1), based on TMPH (Ton Miles Per Hour). The tire - developed to fit Caterpillar® 793F and Komatsu 830E AC models - can increase the amount of material carried per hour, a critical productivity indicator for this segment.  

The new tire, the MICHELIN® XDR250 50/80R57, features significant technical advancements: greater load capacity, lower operating temperature, faster driving speed, higher level of performance for improved productivity and longer life cycle(2).

"Rigid dump trucks are the lifeblood of open pit-mining operations. These tires need to deliver maximum productivity, safety and durability to eliminate downtime," said Jamey Fish, director of earthmover marketing for Michelin North American. "This tire carries a 67-ton nominal load capacity at a faster speed with a longer life cycle. Michelin is delivering solutions that can increase mine profitability through lower operating costs."

With a load capacity that’s 11.6 percent greater than its predecessor the MICHELIN® XDR2 40.00 R57, the MICHELIN XDR250 is the market benchmark for rigid dump trucks.  A new tread pattern incorporates smaller rubber blocks crossed by grooves that optimize air flow and cooling. The tire runs 17 degrees Fahrenheit cooler in the crown, allowing it to carry a heavier load at the same speed or to increase the average operating speed.

To match the growing capacity of this new generation of machines, the MICHELIN XDR250 contains an additional 9.2 percent in air volume. The tire is MEMS-readied (Michelin Earthmover Management System), an integrated sensor system that measures both tire pressure and temperature. Real-time alerts are sent to the mine’s operator in the control room to notify in the event that a tire is overheating or is over- or under-inflated so immediate action can be taken.
