What this component does
Double Coin is a Chinese commercial tire brand — significantly cheaper than Michelin/Bridgestone/Goodyear (typically 40-50% lower per tire). Distributed in North America via CMA. Quality varies but has improved substantially since 2015. Major appeal: budget owner-operators and small fleets who run high-mileage routes and want lower cost-per-mile. Trade-off: shorter tread life, less consistent quality control, and fewer retreading partnerships.

Frequently Asked Questions
What is the Double Coin RT500 (budget all-position)?
Double Coin is a Chinese commercial tire brand — significantly cheaper than Michelin/Bridgestone/Goodyear (typically 40-50% lower per tire). Distributed in North America via CMA. Quality varies but has improved substantially since 2015. Major appeal: budget owner-operators and small fleets who run high-mileage routes and want lower cost-per-mile.
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.
