A Nevada mine running Hitachi haul trucks was inspected by MSHA (Mine Safety and Health Administration) in December, 2015. The inspector noticed that the front struts on a Hitachi EH5000AC were at risk of rubbing on the tires if the vehicle went to full compression. The mine was written up by MSHA and told to repair the trucks. The mine called in its contracted truck maintenance staff, along with Michelin and their own mine tire manager. The first thought was to replace the hubs to push the tires outward, at a cost of $40K per truck. Alternatively, modifying the tires to narrower profiles would cost $120K per truck. The mine tire manager then turned to his RIMEX representative, who proposed an innovative solution to narrow the stock wheels. This strategy was agreed upon, and within three weeks the new wheels were delivered to the mine, at a dramatically lower cost of $19,966.00 per truck!
