What this component does
Michelin XTA is Michelin's leading trailer position tire. Trailer tires are designed differently from steer/drive — they don't drive or steer, just roll, so they prioritize sidewall durability over traction. Trailer position runs 8 tires (2 per side × 4 positions on tandem trailer). Trailer tires typically have the longest service life of any position — 300K-500K+ miles common — because they don't have driving torque or steering loads. Major fleet customers: Werner, Schneider, J.B. Hunt — anyone running 53' dry van trailers.

- XTA (2010–present)Long production run with compound refinements.
Reliability and longevity
Longest-lived position in commercial trucking. 400K-500K mile service life common.
Common problems
Sidewall cuts from curbs/dock approaches (#1 cause of trailer tire damage). Tread separation in heat extremes (less common with modern compounds).
Maintenance schedule
Weekly pressure check (100-110 PSI for trailer 11R22.5). Visual inspection at every trailer pre-trip (driver responsibility).

Frequently Asked Questions
What is the Michelin XTA (trailer tire)?
Michelin XTA is Michelin's leading trailer position tire. Trailer tires are designed differently from steer/drive — they don't drive or steer, just roll, so they prioritize sidewall durability over traction. Trailer position runs 8 tires (2 per side × 4 positions on tandem trailer). Trailer tires typically have the longest service life of any po
How long do commercial truck tires last?
Service life varies by position and tire type. Steer tires: 200,000-350,000 miles (fuel-economy tires are at the lower end; aggressive treads at the upper end). Drive tires: 200,000-300,000 miles in highway use; 130,000-220,000 in vocational/severe service. Trailer tires: 300,000-500,000+ miles (longest-lived because they don't drive or steer). Retreading extends casing life — a quality Michelin or Bridgestone casing can be retreaded 2-3 times, giving total service life of 600,000-1,000,000 miles for the casing across multiple tread surfaces.
Is the SmartWay EPA program worth it?
EPA SmartWay verifies commercial tires that meet rolling-resistance thresholds for fuel economy. SmartWay-verified tires typically save 4-7% fuel vs non-SmartWay tires — meaningful at $0.05-0.10 per mile in fuel cost. Major shippers (Walmart, Target, Amazon) increasingly require SmartWay tires in carrier contracts. SmartWay verification is a Tier 1 spec for any fleet running federally-rated lanes. Brands meeting SmartWay: Michelin Energy line, Bridgestone Ecopia, Goodyear Fuel Max, Continental Eco Plus.
What tire pressure should I run?
Recommended pressure varies by tire size and load. For 11R22.5 (most common Class 8 size) on highway tractor: 110 PSI all positions standard. For 295/75R22.5 wide-base (single tire replacing dual): 110-120 PSI. For 22.5 dual-position drive tires: 100-110 PSI. CRITICAL: 10% underinflation cuts tread life by 25% and adds 1% rolling resistance (worse fuel economy). Daily visual + weekly gauge check is non-negotiable for fleet operating costs.
Can I retread my tires?
Yes — retreading is the dominant practice in commercial trucking. A quality casing (Michelin, Bridgestone, Goodyear, Continental) can be retreaded 2-3 times, with each retread costing 30-40% of a new tire. Casings older than 7 years are typically rejected for retreading per industry standards. Michelin Retread Technologies, Bridgestone Bandag, Goodyear Treadmax — the three major retread networks. Avoid retreading cheap import casings — quality control issues make them unreliable.
How does FMCSA regulate tire condition?
49 CFR 393.75 requires: tread depth at least 4/32" on steer tires, 2/32" on all other positions. Tires must be free of body ply or sidewall cord exposure. No tire installed without a stem cap. Tubeless tires must have a valid tread depth. Many fleets replace at 4/32" all positions to have safety margin and avoid roadside-inspection citations. Tire violations are common Vehicle Maintenance BASIC citations — severity 8 weight, often OOS-eligible.
What's the difference between steer, drive, and trailer tires?
Steer tires: front position, optimized for steering responsiveness + cornering grip. Five-rib designs for stability and water evacuation. Closed-shoulder pattern for fuel economy. Drive tires: rear powered axles, aggressive lug pattern for traction (especially in wet/loose conditions). Higher rolling resistance than steer for grip. Trailer tires: free-rolling, no traction or steering load — optimized for sidewall durability and long service life. Tubeless designs typical. Wrong-position tire installation hurts performance and may violate FMCSA tire-fitness rules.
