Open Country AT3 Tread Pattern and Compound A specialized, all-season, cut-and-chip resistant tread compound is molded into the Open Country AT3's symmetric tread pattern, utilizing an evenly distributed void area design. The pattern is engineered to enhance off-road traction and increase block rigidity for better dry handling and stability, while still incorporating comfortable and quiet on-road operation. The wet traction-focused compound of the Open Country A/T III, along with 3D Multi-Wave Sipes, increase wet traction and stability. Generous lateral grooves increase hydroplaning resistance while also bolstering traction in snowy conditions, and help the tire earn the 3PMSF symbol. The Toyo Open Country AT3 offers two distinct sidewall designs built into all sizes, allowing for a subtle customization of the vehicle's look. One side features wraparound shoulder elements with a solid design. The opposite side, and sidewalls with outlined white letters, feature a similar block design but with the elements visually broken up by accent lines splitting the block area. Toyo Open Country AT3 Internal Construction The internal construction of the Open Country AT3 utilizes a durable, two-ply polyester casing, providing a robust foundation for twin, high-strength steel belts. A single, nylon reinforcement ply is added for further durability and increased high-speed capability. Note: While non-winter tires featuring the three-peak mountain snowflake (3PMSF) symbol may provide additional longitudinal snow traction beyond what all-season (M+S) tires not bearing the symbol can deliver, they do not match the capability of a true winter tire in all adverse weather conditions.ABOUT THIS TIRE TIRE LINE FEATURES Advanced tread design Abundant siping Deep grooves Rugged construction BENEFITS Long-lasting treadlife Long-lasting treadlife Meets the industry?s severe snow requirements and carries the three-peak mountain snowflake symbol Quiet highway ride Powerful off-road traction Quiet highway ride Exceptional wet braking Powerful off-road traction Exceptional wet braking Meets the industry's severe snow requirements and carries the three-peak mountain snowflake symbol WARRANTY Mileage Warranty: 50,000 SPECIFICATIONS 50k Warranty Speed Rating 112 Load Index 121 Maximum Load 3195 Seasonality All-Season Run-Flat No Terrain All-Terrain EV Flag LT315/70R17 121/118S D
