Michelin X-One Line Energy D 445/50R22.5

Choose the Michelin X-ONE LINE ENERGY D 445/50R22.5 wide-base drive-axle tyre to lower total cost of ownership on long-haul. Replacing duals with a single tyre reduces tare weight, increases payload and cuts rolling resistance for real fuel savings. Its robust casing and optimised tread deliver confident wet traction, stable handling and even wear for long life. Designed for multiple retreads, it reduces cost per kilometre and supports your sustainability goals. Fit Michelin quality and keep your fleet moving further, safer and more efficiently.

Wide-base single configuration. By replacing duals with one wide-base tyre on the drive axle, the Michelin X-One Line Energy D 445/50R22.5 lowers unsprung mass and reduces aerodynamic drag around the wheel ends, cutting parasitic losses at highway speeds while maintaining a broad, stable contact patch for torque transfer. The wider footprint distributes load more evenly across the tread to mitigate shoulder scrub and irregular wear, improving kilometre-to-removal and enabling higher payload potential within NZ axle-weight limits. Fewer rims, valves and wheel-end components streamline maintenance and reduce failure points, while improved rolling efficiency translates to measurable fuel savings and lower CO2 per tonne-km on long-haul routes.

Low rolling resistance compound. An energy-optimised tread and undertread compound minimises hysteresis through advanced polymer networks and high-dispersion silica, reducing heat build-up and deformation losses under steady-state cruise. This keeps the casing of the Michelin X-One Line Energy D 445/50R22.5 running cooler, preserving belt-edge integrity and bead durability, while delivering consistently low rolling resistance across the full wear life. The result is fuel consumption reduction without compromising wet grip, supported by a compound gradient that decouples tread cap traction from undertread energy loss for best-in-class total cost of ownership on New Zealand linehaul.

Regenion evolving tread grooves. Full-depth, 3D metal moulding creates self-regenerating channels that open as the tyre wears, maintaining effective void ratio and fresh biting edges for reliable traction and water evacuation throughout the life of the Michelin X-One Line Energy D 445/50R22.5. Interlocking geometry stabilises tread blocks under high drive torque to limit squirm, reducing heat and heel-and-toe wear on coarse chipseal while preserving wet grip later in life. This extends usable tread depth, helps resist stone retention, and keeps stopping and traction performance closer to new-tyre levels, supporting safety and uptime between scheduled rotations.

Infinicoil continuous reinforcement. A single, continuous steel cable wrapped circumferentially beneath the tread provides exceptional crown stability, controlling growth at speed and keeping the footprint uniform under heavy loads and torque spikes. On the Michelin X-One Line Energy D 445/50R22.5 this translates to precise tread stiffness distribution, reduced irregular wear initiation at the shoulder and belt edges, and improved driver feel in lane changes and grades. Enhanced crown integrity also protects against penetrations and separations, boosting casing longevity and retread acceptance for multi-life economy in demanding NZ freight operations.

Powercoil durable casing. High-tensile, lightweight steel cords in the carcass and bead area increase fatigue resistance while lowering internal heat, delivering a robust yet efficient casing architecture for the Michelin X-One Line Energy D 445/50R22.5. This advanced construction, paired with an air-retentive inner liner and reinforced bead bundle, maintains inflation stability to protect the footprint and curb rolling resistance creep over time. The durable casing supports multiple Michelin Remix retreads, spreading capital cost across successive lives, and is engineered to withstand long-haul thermal cycles and the abrasion of New Zealand’s coarse road surfaces without compromising structural integrity.
