Michelin rolls out tire for largest wheel loader

Michelin is globally introducing the 70/70R57 MICHELIN X MINE L4** tire, its newest offer in earthmover tires for the Komatsu WE2350/P&H L2350 large wheel loader used in surface mining.

The new release radial delivers improved mobility and productivity thanks to three times the tramming speed of the competitor tire. It also does not require chain fitments on the rear axle due to its robust radial design, resulting in reduced tread wear, an optimized and even footprint, less deformation of the contact patch on the ground, and an overall life expectancy increase of 50% or more.

“As part of our Michelin Better Mining approach, we strive to provide the mining industry with innovative solutions that add significant value for our customer operations,” said Senior Vice President for Michelin Mining Adam Murphy.

“The new 70/70R57 MICHELIN X MINE L4** tire builds on our history of innovation with the first radial tire for the world’s largest wheel loader, providing a step-change in the mines’ productivity, while also contributing to their safety and sustainability.”

The 70/70R57 MICHELIN X MINE L4** tire is designed to run cooler than the competition, thanks to its radial construction and compounds that keep the tire at an optimal temperature at greater speeds, maintaining a temperature difference of 10° (Celsius) cooler on the front axle versus the competition in similar conditions. 

It also offers excellent protection and wear resistance due to the steel cables in the tire, giving the tire a robust architecture and outstanding endurance under the harshest mining conditions. 

The 70/70R57 MICHELIN X MINE L4** tire is engineered to meet traction performance standards on both wet and dry surfaces, and is ready for use with the MEMS tire pressure monitoring system (TPMS), so that mine operations can improve uptime and experience seamless connectivity.

Designed to be safe, smart and more sustainable, the 70/70R57 MICHELIN X MINE L4** tire is ready to tackle the most rugged environments.

“The Carajas mine is a very large geographic area. Strategically, we need to be able to move these machines around according to the daily production schedule,” said Frederico Sa, Carajas Mine tire manager, Brazil, who tested the 70/70R57 MICHELIN X MINE tires on its site. 

“Radial tires improve mobility so we can work more and have more options and better mobility with our machines onsite. This benefit will be captured according to our production strategy.”
