Michelin North Americ is completing the MICHELIN XTRA LOAD lineup with the addition of the 21.00R33 dimension for rigid dump trucks (RDT). The new MICHELIN XTRA LOAD GRIP and the MICHELIN XTRA LOAD PROTECT will allow users to increase load capacity by 10 percent or accommodate more distance per hour to maximize productivity.
Both the MICHELIN XTRA LOAD GRIP and the MICHELIN XTRA LOAD PROTECT will be offered in A4 and B rubber compounds.
"The MICHELIN XTRA LOAD tire line is complemented by the MICHELIN XTRA DEFEND line for articulated dump trucks," said Sarah Robinson, B2B mining marketing manager for Michelin North America. "This Michelin offer for transport trucks in quarries and mines provides a modern solution to maximize the amount of material loaded into these trucks while still delivering traction, damage resistance and increased tire life."
The new MICHELIN XTRA LOAD tire is available for two surface rigid dump truck applications:
for hard, sharp, abrasive conditions on flat, dry surfaces, where the priority is protection and damage resistance — conditions often found in quarries and construction sites. This application is for customers who want to carry up to 10 percent more load or increase the distances they carry up to a maximum speed of 21 mph. With an 8 percent longer wear life, the revolutionary tread pattern contains a greater volume of tread rubber and has better load distribution across the contact patch. The interlocking blocks and improved heat dissipation yield a cooler running tire that allows increased speeds. Corrosion-proof cables within the tire structure increase aggression resistance.
for soft, loose, muddy ground conditions in mining and quarry operations on slopes and inclines, where the priority is high grip and traction. A reinforced casing gives the tire a 10 percent more load capacity per machine — a huge increase in productivity when multiplied by the number of cycles made daily. The tread is comprised of 30 percent more biting lug edges, which improves braking, cornering and acceleration in loose ground conditions. The tire can handle speeds up to 21 mph thanks to cooler internal running temperatures. The tire also provides 8 percent longer wear life with more rubber in the contact patch and improved damage resistance with corrosion-proof steel cables.
Productivity is a function of load and distance covered in an hour, as measured by ton miles per hour (TMPH). For the XTRA LOAD PROTECT, the TMPH is increased by at least 9.3 percent and up to 69 percent depending on the specific compounding when compared with previous Michelin ranges. For the new XTRA LOAD GRIP, the TMPH is increased by at least four percent and up to 31 percent depending on the specific compounding when compared with previous Michelin ranges. This extended load and speed capability will allow users to optimize machine cycles and increase productivity. Greater volume of tread rubber in contact with the ground contributes to better load distribution, improved wear resistance and increased tire life.
The XTRA LOAD series is also available in sizes 18.00R33 and 24.00R35.
