Product Details

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

Advanced Tread Technology:

  • New Tread Compound: Engineered for confident wet braking and handling with superior cut-and-chip resistance for durability
  • Aggressive Tread Design: Features a more evenly distributed void area that provides excellent off-road grip while delivering a surprisingly quiet and comfortable ride
  • 3D Multi-Wave Sipes: Enhance traction on all surfaces including snow while reducing irregular wear for longer tread life
  • Staggered Shoulder Lugs: Improve off-road traction with aggressive biting edges and provide better worn appearance throughout the tire's life
  • Increased Lateral Grooves: Enhance both on-road handling stability and off-road traction by increasing tread block rigidity
  • Stone-Ejecting Blocks: Actively eject stones from grooves to prevent damage and maintain performance

Warranty Coverage:

  • 65,000-mile treadwear warranty for P-Metric and Euro-Metric sizes
  • 50,000-mile treadwear warranty for LT and Flotation sizes
  • Staggered fitments: rear tires eligible for 50% of stated mileage warranty
  • 500-mile trial offer for customer satisfaction

The Toyo Open Country AT III strikes the ideal balance between rugged off-road capability and refined on-road manners, making it perfect for drivers who demand versatility from a single tire.
