Michelin Americas Truck Tires has launched the X Line Energy Z for linehaul steer applications. The SmartWay-verified tire is guaranteed to deliver 20% more mileage than leading competitor equivalents, Michelin says, while also delivering 5% better rolling resistance than the  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 X Line Energy Z steer tire can be combined with the following tires on every axle to create complete SmartWay linehaul packages:

Dual applications — the X Line Energy D drive tire and Energy T trailer tire.

Wide-base applications — the X One Line Energy D drive tire, and X One Line Energy T trailer tire.

The new steer tire features a patented “dual-energy compound” tread. The top layer controls tread stiffness and stress to reduce irregular wear. The bottom layer provides fuel efficiency and retreadability to minimize internal casing temperatures for low rolling resistance and extended casing life.  Decoupling grooves and directional miniature sipes promote even tire wear, Michelin says.

The 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 now in 11R22.5, 275/80R22.5, 11R24.5, and 275/80R24.5 sizes in both G and H load ranges.
