Michelin Americas Truck Tires, a division of Michelin North America, Inc., is launching the Michelin X Line Energy Z for heavy-duty line-haul steer applications. (Steer tires are the tires on the front steering axle of a tractor-trailer. Drive tires are designed for the tractor’s drive axles, and trailer tires are designed for the trailer axles.)
The SmartWay-verified tire is guaranteed to deliver 20% more mileage than leading competitor line-haul steer tires, while also delivering 5% better rolling resistance than the Michelin XZA3+ tire it replaces. It features a new, ultra-fuel-efficient casing, so the improvement in rolling resistance follows the tire throughout its life—from new to retread.
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 better 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. This includes coverage against defects in workmanship and materials for 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 1 March in 11R22.5, 275/80R22.5, 11R24.5 and 275/80R24.5 sizes in both G and H load ranges.
