The PRO Range from Michelin Arrives to Market

The brand new Michelin PRO range for machinery that operate in underground mines, has been designed to perform well in especially aggressive conditions in this type of operations.

The new series Michelin PRO, XSM D2+ PRO and X MINE D2 Pro has been improved and reinforced as much in the sidewalls as in the tread itself. Underground mining poses the maximum challenge for tyres that operate in the rocky and fragmented terrain, which in turn adds to the problem of tyre rubbing against the walls of the tunnel. This particular usage generates cuts and rifts in the sidewalls of the tyres that can propagate and lead to the break down in the structure of the casing.

The new series from Michelin all benefit from an enhanced casing design that incorporates increased thickness in the rubber in the product’s most vulnerable areas, new compounds and NRF technology, which include 2 protective layers of crossed nylon, which is coated in a high-resistance rubber compound in the sidewall of the tyre that reduces the risk of the cuts spreading.

The tread area has been additionally reinforced with a new design and configuration of the layers of reinforcement to improve the resistance to these conditions and provide further protections against oxidation.

There has also be an increase of up to 18% in the loading capacity of the Michelin Pro series that has been achieved through the aforementioned reinforced casing and bead design. These two allow the tyre to work at a lower inflated pressure and therefore reduce the risks of cuts and abrasions.

On top of this, the useful life of the tyres has been improved through special new compounds that yield additional protection and resistance to damage. The new Michelin PRO, XSM D2+ PRO and X MINE D2 Pro portfolios were made available globally from the start of July.
