Product Details

The Toyo Open Country AT III is an all-season, all-terrain tire designed for light trucks, SUVs, and CUVs that combines aggressive off-road capability with refined on-road performance. This tire carries the Three-Peak Mountain Snowflake (3PMSF) symbol, certifying it meets required performance criteria for use in severe snow conditions, making it a true year-round tire for adventure seekers.

Advanced Tread Design:

  • New tread compound provides confident wet braking and handling while delivering cut-and-chip resistance for durability
  • More evenly distributed void area ensures excellent off-road grip and a quiet, comfortable ride on highway
  • Staggered shoulder lugs enhance off-road traction with aggressive biting edges
  • Increased lateral grooves improve water evacuation and traction on all surfaces
  • 3D multi-wave sipes enhance traction on wet, dry, and snowy surfaces while reducing irregular wear
  • Stone-ejecting blocks protect the casing by ejecting stones from grooves

Performance Benefits:

  • Increased tread block rigidity delivers excellent handling stability on pavement
  • Aggressive design maintains better worn appearance throughout tire life
  • Balanced void ratio provides the off-road traction you need without sacrificing on-road comfort

Warranty Coverage:

  • 65,000 mile treadwear warranty for P-Metric and Euro-Metric sizes
  • 50,000 mile treadwear warranty for LT and Flotation sizes
  • 500 mile trial offer for customer satisfaction
