Product Details

The Sumitomo ST770 is a commercial-grade regional trailer tire engineered specifically for spread-axle highway fleets operating medium-duty trucks. This 385/65R22.5 tire features a wide-base design that provides excellent stability and load distribution for free-rolling trailer applications.

Key Features:

  • Wide-base single tire configuration reduces overall vehicle weight compared to dual tire setups
  • Advanced tread compound optimized for regional haul applications with mixed highway and secondary road use
  • Robust casing construction rated for 158 load index (9,250 lbs capacity per tire)
  • Speed rating K (68 mph maximum sustained speed)
  • Tubeless (TL) design for easier maintenance and reduced downtime
  • 18-ply rating provides exceptional durability and puncture resistance
  • Specialized tread pattern promotes even wear and extended tire life in trailer positions

Ideal for fleet operators seeking to maximize payload capacity while minimizing weight penalties, the ST770 delivers reliable performance in demanding regional and highway trailer service.
