Come May 1, Michelin customers will be able to order the company's lowest-rolling-resistance drive tire yet. The X One Line Energy D2, a wide-base single tire, is designed for line haul, dry van truckload, and refrigerated truckload applications. It has already demonstrated fuel savings of more than $2,300 per year compared to a leading competitor’s tire, according to company officials.
Michelin’s X One Line Energy D2 tire, introduced at the American Trucking Associations’ Technology & Maintenance Council annual meeting in Orlando, comes in a 445/50R22.5, load-range L with 20/32 tread depth. It is a directional tire for the first half of its life, providing improved resistance to irregular wear for increased driver confidence and long tread life, according to the company.
It replaces the X One Line Energy D tire, launched in 2012.
Michelin’s Regenion evolving tread design gives the Michelin X One Line Energy D2 tire stability in all weather conditions for North American operations. The straight, pass-through grooves have features that appear as the tire wears, helping give traction throughout the life of the tire. The rectangular bead minimizes fatigue to extend casing life, which is designed for maximum retreadability.
The tire’s compact design produces less tread squirm and provides energy conservation for fuel efficiency. Its advanced tread compounds save up to $2,317* per year in fuel, achieving the SmartWay standard. Its ultra-rolling-resistance levels are designed to exceed Greenhouse Gas Phase 2 (GHG2) and California Air Resources Board (CARB) requirements for reduced carbon output.
*The X One Line Energy D2 tires save $2,317 per year according to third-party testing by MVTS of 445/50R22.5 drive tires. The tires were fitted on 2019 International LT 625’s with Cummins X15 15L engines and Eaton Endurant 12-speed automated manual transmissions. Each pulled identical 53-fooot Hyundai dry vans loaded to 78,000 lbs. and running at 65 mph. Savings estimates are based on $2.551/gallon fuel price (2020 average). Actual results may vary.
