Michelin completes rigid dump-truck tire lineup

GREENVILLE, S.C. — Michelin North America Inc. is completing the Xtra Load lineup with the addition of the 21.00R33 dimension for rigid dump trucks.

The new Xtra Load Grip and the Xtra Load Protect will allow users to increase load capacity by 10% or accommodate more distance per hour to maximize productivity, the company said.

Both tires 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," Sarah Robinson, B2B mining marketing manager for Michelin North America, said.

"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 Xtra Load Protect is designed 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, Michelin said.

This application is for customers who want to carry up to 10% more load or increase the distances they carry up to a maximum speed of 21 mph. With 8% longer wear life, the 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.

The Xtra Load Grip is made 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% more load capacity per machine. The tread consists of 30% more biting lug edges, which improves braking, cornering and acceleration in loose ground conditions, Michelin said.

The tire can handle speeds up to 21 mph thanks to cooler internal running temperatures. The tire also provides 8% longer wear life with more rubber in the contact patch and improved damage resistance with corrosion-proof steel cables.

The Xtra Load series is also available in sizes 18.00R33 and 24.00R35.
