Equipped for all seasons with a severe snow rating & full-depth 3D-locking sipes. Trail ready and engineered to explore using a tread compound designed for chip/tear durability meant for occasional gravel road usage. the Trail-Terrain T/A tire is designed to resist chipping and tearing in occasional gravel road usage. The serrated shoulder design is optimized for soft-soil traction in light off-pavement situations without compromising road noise. It also continues to provide traction long after the mercury drops. The full-depth 3D sipes are engineered to create plenty of power and grip over the full life of the tire, which earned the three-peak mountain snowflake rating for severe-snow performance.
