Get technical:

Built for fleets seeking lasting cost-per-mile performance, the Milestar SL177-S is a SmartWay-verified commercial tire designed for regional and long-haul steer applications. It is engineered for semi-trucks, big rigs, and highway tractors that require dependable steer-axle capabilities. The tire's key strengths include optimized fuel savings, responsive handling, and a reinforced construction that supports a long service life and retreadability.



Features & Benefits

  • A five-rib tread pattern promotes smooth highway handling and enhanced steering stability on extended routes.
  • The integrated decoupling groove aids in overall vehicle stability while contributing to improved fuel efficiency.
  • Additional siping across the tread blocks enhances grip in both wet and dry weather conditions for reliable year-round performance.
  • Solid shoulders combat irregular treadwear over time to optimize the tire's usable tread life.
  • A reinforced casing protects against road hazards to support a long service life and high retreadability.
