Michelin proves XDR3 heavy tyre over 25 million km
Michelin delivers upgraded earthmover tyre after tests equivalent to circling the earth 625 times
Michelin has launched the 40.00R57 and 53/80R63 variants of its new XDR3 tyres for rigid dump trucks in surface mine applications, having tested the tyre over more than 25 million kilometres, which is the equivalent of circling the earth 625 times.
Michelin’s R&D teams have spent more than six years developing XDR3, which has responded to the demands of customers with several new features that together have increased the life of the tyres by a minimum of 10% compared to its predecessor, the Michelin XDR2.
First, a new tread pattern has improved the heat dissipation capacity – keeping the tyres 8°C cooler in the tread area. It also ensures that a greater volume of tread is in contact with the ground at any given time, improving load distribution and reducing wear, especially during cornering.
The high-strength steel cables used in the tire’s casing are meanwhile 10% stronger than in the XDR2 and are encapsulated in rubber to prevent the spread of corrosion within the casing, extending the life of the tyres.
The XDR3 is also equipped with the Michelin Earthmover Management System (MEMS), which means it is fitted with data sensors capable of capturing and transmitting temperature and pressure information in real time.
The 40.00R57 variant of the XDR3 is available now, while the 53/80R63 will be available from January 2017.
