MICHELIN Launches Latest Version of its Industry-Leading Line-Haul Steer Tire

MICHELIN(®) X(®) Line(TM) Energy Z guarantees 20 percent more mileage than leading competitors

by David T Little

Michelin North America (Canada) Inc. is launching the MICHELIN(®) X(®) Line(TM) Energy Z for line-haul steer applications. The SmartWay(®)-verified tire is guaranteed to deliver 20 percent more mileage than leading competitor line-haul steer tires((1)), while also delivering 5 percent better rolling resistance than the MICHELIN(®) XZA3(®)+ tire it replaces((2)).  It features a new, ultra-fuel-efficient casing, so the improvement in rolling resistance follows the tire throughout its life -- from new to retread.


"Michelin is known for providing industry-leading mileage and even wear.  The MICHELIN X Line Energy Z continues that evolution, while also increasing fuel efficiency, so fleets get the best of both worlds." said Thomas Stacey, country operational marketing manager for truck tires, Michelin North America (Canada) Inc. "Allowing fleets to get the most out of their line-haul steer tires is what the new MICHELIN X Line Energy Z tire is all about."


The MICHELIN X Line Energy Z features a patented dual-energy compound tread. The top layer controls tread stiffness and stress to reduce irregular wear.  Decoupling grooves and directional miniature sipes promote even tire wear. The bottom layer provides ultra-fuel efficiency and retreadability to minimize internal casing temperatures for low rolling resistance and extended casing life.


Providing maximum retreadability and a casing designed for endurance, the MICHELIN X Line Energy Z comes with the 7/7/3 manufacturer's limited casing warranty((3)). This includes coverage against defects in workmanship and materials for 1,130,000 kilometers (700 000 miles), seven years or three retreads from the date of manufacture when retreaded by an authorized Michelin Retread Technologies (MRT) dealer. The tire is available March 1 in 11R22.5, 275/80R22.5, 11R24.5 and 275/80R24.5 sizes in both G and H load ranges.


The MICHELIN X Line Energy Z steer tire can be combined with the following tires to offer a complete SmartWay line-haul solution -- bringing excellent mileage, even wear and fuel efficiency to every axle:
