Tires get a lot of wear and tear in underground mining, leading to downtime as miners replace them. Michelin’s new X Mine D2 Pro and XSM D2+ Pro line of tires have been specifically redesigned with underground conditions in mind. The new models can bear an 18 per cent larger load than their predecessors. Michelin said the new tires will also have a longer life, thanks to new materials. The crossed nylon cords encased in rubber allow the treads to take more weight and tolerate more buffeting from rock and water without losing their integrity. Plus, new technology supports the sides of the tires to prevent caving from side-swipes.
