GREENVILLE, S.C.  — Michelin North America on October 1 launched the MICHELIN X Line Energy D+ tire, its new ultra-low rolling resistance dual-drive line-haul tire, to the North American replacement market.

The tire was developed through an advanced-engineering project over three years with the objective of reducing the fuel consumption of Freightliner’s next-generation Cascadia Class 8 heavy-duty trucks and yielded a product with the lowest rolling resistance offered by Michelin in a dual-fitment drive tire, according to Adam Murphy, vice president B2B marketing for Michelin North America.

“The MICHELIN X Line Energy D+ sets a new standard for Michelin,” Murphy said. “With about 35 percent of vehicle fuel consumption attributed to overcoming tire rolling resistance, this tire delivers both fuel savings while providing exceptional traction for driver confidence.”

As Michelin’s most fuel-efficient drive tire for long-haul applications, the MICHELIN X Line Energy D+ tire 275/80R22.5 size is designed for fleets looking to save hundreds of dollars in fuel spend with an estimated annual fuel savings of $725, Murphy said, adding that the new tire meets SmartWay requirements and is greenhouse-gas 2 regulation and CARB compliant.

The X Line Energy D+ features a tread compound designed for exceptional fuel efficiency, Murphy said.

The Infini-Coil technology wraps 1/8 mile of steel cable around the durable casing to eliminate casing growth and ensure a consistent footprint and even wear. The casing is designed with high-tensile-strength steel belts capable of supporting multiple retreads.

With the ability to get a tractor up and running 35% faster than a leading competitive tire, Murphy said the X Line Energy D+ incorporates interlocking, edge-biting tread sipes and regenerative tread grooves designed to provide superior grip and traction throughout the life of the tire. Interlocking siping and regenerating features are designed to provide biting edges throughout tread life.

“Providing maximum retreadability and a casing designed for endurance, the X Line Energy D+ comes with the 7/7/3 manufacturer’s limited casing warranty,” Murphy said. “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 in the United States and Canada.
