The Michelin X ONE LINE ENERGY T2 445/50R22.5 is a SmartWay-verified low-rolling-resistance radial trailer tire optimized for line-haul commercial applications, boasting 20-ply construction, a 161L load index, L speed rating (up to 75 mph), 12/32-inch tread depth, and a 39.4-inch overall diameter for exceptional fuel efficiency and longevity.
Key Benefits
Fuel Efficiency
Minimizes internal heat and lowers rolling resistance, reducing fuel consumption.
Dual-compound tread: a cooler base layer for efficiency and a top layer for wear and grip.
Even, Long Tread Wear
Micro-siping prevents irregular wear and provides biting edges for traction.
Optimized contact patch and dual tread layers contribute to uniform wear.
Durability
Infini‑Coil® steel cable around the casing maintains footprint stability and reduces casing growth.
Curb guards and reinforced sidewalls reduce sidewall damage and unexpected downtime.
Traction
Good wet-road grip due to tread design and micro-siping, even as the tire wears.
Retreadability
Built for long casing life, suitable for retreading.
Line-Haul Optimized
Designed for line-haul trailer applications, balancing fuel savings, mileage, and durability.
