Product Details

The Toyo Open Country AT III is an all-season/winter all-terrain tire designed for light trucks, SUVs, and CUVs. This tire carries the Three-Peak Mountain Snowflake (3PMSF) symbol, certifying its capability in severe snow conditions while delivering exceptional performance on and off the road.

Advanced Tread Technology:

  • New tread compound and aggressive design for enhanced durability and traction
  • More evenly distributed void area optimizes water evacuation and off-road performance
  • 3D multi-wave sipes enhance on and off-road traction in varying conditions
  • Increased lateral grooves improve wet weather handling and braking confidence
  • Stone-ejecting blocks prevent gravel retention and protect the casing

Performance Features:

  • Staggered shoulder lugs provide excellent off-road grip and enhanced sidewall protection
  • Increased tread block rigidity delivers excellent handling stability on paved roads
  • Cut-and-chip resistant compound withstands rugged terrain
  • Engineered for a quiet and comfortable ride despite aggressive tread pattern
  • Confident wet braking and handling in rain and light snow

The 235/80R18 size with 121/118S service description offers robust load capacity and speed capability for full-size trucks and SUVs. Whether you're commuting on highways or exploring unpaved trails, the Open Country AT III delivers year-round versatility with genuine winter capability.
