BFGoodrich All-Terrain T/A KO2 Tires are On Sale and Ship Free! BFGoodrich All-Terrain T/A KO2 Tires use CoreGard Technology: Split & bruise resistant sidewall rubber, derived from BFGoodrich's race proven Baja T/A KR2 tire. Increased rubber thickness, extending down the sidewall to protect more of the critical sidewall failure zone. Advanced Deflection Design deflects protruding objects from snagging & splitting the sidewall. Advanced tire footprint shape results in more evenly distributed stress, for longer more uniform wear. Interlocking Tread Design provide increased tread block stability, for more even wear over the long haul. Stone Ejectors rejects stone retention & providest protection against stone drilling. Upper Sidewall Traction Bars provide increased mud, snow & rock traction, especially in aired-down driving situations. Mud-Phobic Bars in the shoulder tread area help to release compacted mud for enhanced traction in muddy and soft soil conditions. Serrated Shoulder Design provide greater maneuverability in soft soil and deep snow conditions. Locking 3-D Sipes provide more biting edges for significantly increased snow traction. 3-Peak Mountain Snowflake Rated: Exceeds Rubber Manufacturer Association (RMA) Severe Snow Traction requirements.
