The Subaru Ascent is heavy enough that a mediocre winter tire shows its limits fast, especially braking downhill into a Calgary intersection with a full load of passengers and gear. The Yokohama iceGUARD G075 carries a twin steel belt and nylon-reinforced casing under a directional winter tread with 3D triple sipes, rated three-peak mountain snowflake for severe snow service, and sized specifically for the Ascent's real-world fitments. The 245/60R18 No Lift size is a genuine factory-matching option that most winter tire lines don't offer for this vehicle, clearing at stock ride height with no suspension changes needed. The 255/70R18 Aggressive size is built for an Ascent running a lift kit and wanting more sidewall and tread depth for backroad driving once the snow piles up. Canada-wide shipping and duties included from Flat 4 Offroad in Calgary.
