Michelin launches surface mining tyre

Michelin introduced a new tyre, aiming at reducing the cost per ton by improving operational efficiency and ensuring safety, for surface mining operations. The new MICHELIN XDR3 responds to the needs of mine operators by incorporating three key innovations, which together increase tyre  life by a minimum of 10%  compared to its predecessor, the MICHELIN XDR 2.

The 40.00 R 57 MICHELIN XDR3 will be available from September 2016 and the 53/80 R 63 from January 2017.

Compared with its predecessor this new tread pattern offers multiple benefits. It offers better endurance due to improved heat dissipation capabilities – 8°C cooler in the tread area. A greater volume of tread rubber is in contact with the ground which improves wear and ensures better load distribution throughout the contact patch due to a lower contact pressure. Finally, interlocking shoulder blocks resist excessive movement during cornering and further reduce tire wear.

“An exclusive new mixing process ensures a more uniform composition of rubber compounds and a superior level of carbon black dispersion that increases wear resistance. Each unique compound offers specific performance characteristics adapted to site conditions and usage, from high wear resistance to high thermal capacity for speed,” said the company.

The high-strength steel cables used in the tyre’s casing are 10 % stronger than in the XDR2 and are encapsulated in rubber to prevent the spread of corrosion within the casing, which extends the life of the tyre.

The MICHELIN XDR3 is also MEMS1 ready. This means that it is possible to quickly and easily install state-of-the-art data sensors to capture and transmit temperature and pressure information in real time.

“Michelin’s R&D teams spent more than six years developing this new tire to ensure that it fully meets the expectations and needs of customers and during the extensive testing process more than 25 million kilometres were travelled, which is the equivalent of circling the earth 625 times,” said the company.
