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. The project yielded a product with the lowest rolling resistance offered by Michelin in a dual-fitment drive tire, the company says.
“The Michelin X Line Energy D+ sets a new standard for Michelin,” says Adam Murphy, vice president, B2B marketing, Michelin North America. “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.”
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, the company says. This tire meets SmartWay requirements and is greenhouse-gas 2 regulation and CARB compliant.
The X Line Energy D+ features a tread compound designed for fuel efficiency. The Infini-Coil technology wraps 1/8 mile of steel cable around the casing to eliminate casing growth and ensure a consistent footprint and even wear. Michelin says the casing is designed with high-tensile-strength steel belts capable of supporting multiple retreads.
The X Line Energy D+ incorporates interlocking, edge-biting tread sipes and regenerative tread grooves designed to provide grip and traction throughout the life of the tire. Interlocking siping and regenerating features are designed to provide biting edges throughout tread life, the company says.
The X Line Energy D+ comes with warranty 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 dealer.
