It starts with picking the right tire.
And just because all tires are round and
black does not mean they’re all the same.
Today’s heavy equipment tires offer a
diverse range of technological improvements over designs of just a few years
ago. Here’s a guide to what the major
manufacturers are producing.
A new retread option, the Michelin XZY3
Pre-Mold, brings all the technological innovations of the company’s new tires to a retread
product with a heavy duty, thick tread and
anti-cut/anti-chip properties for the on/
off road market. The XZY3 Pre-Mold tread
comes in rolls and multiple widths and is
applied to casings at Michelin authorized franchises. The company also
uses two different rubber compounds
co-extruded in the XYZ3 product. “It
uses a cooler running compound by the casing to keep heat off the casing
for better performance and longevity,” says Tom Brennan, vice president
of sales for retreading at Michelin. “Then the tread that goes against
the road can be a different compound and be more aggressive, or fuel
efﬁcient or offer less rolling resistance if needed.”
