The new mining tire from Michelin for 250-ton rigid dump trucks is claimed to increase hauling productivity by at least 24% based on 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.
The XDR250 features significant technical enhancements enabling a greater load capacity, lower operating temperature, faster driving speed, higher level of performance for improved productivity and longer lifecycle.
A new tread pattern incorporates smaller rubber blocks crossed by grooves that optimize air flow and cooling. The tire runs 17°F cooler in the crown, enabling it to carry a heavier load at the same speed or to increase the average operating speed.
It also contains an additional 9.2% in air volume and is equipped with Michelin’s 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 so immediate action can be taken in the event that a tire is overheating or is over- or under-inflated.
