I give this tire only 4/5 it's no match for my Nokian Hakka RSi/R7 and Gislaved NordFrost. On a straight line in snow, it's ok: it stops when I move at city street speed. But it starts sliding on a normal turn at reasonable speed on city street during peak hours with 10cm of fresh snow (I don't drive fast in city or on residential streets). At highway speed on snowy hiway I would be very cautious.
The fact that it slides on normal turns disappoints me!
(But its price is only half of Hakka or Gislaved :) ).
And yes, I drive in Canadian winter to go skiing and in snow storms.
These tires are impressive. Coupled with the AWD of the Outback, they have never slipped once ! Driving at speed limits, cornering, braking and acceleration on snow is a no brainer. In the dry they really do stick like glue to the road with very positive steering. Did I mention quiet and smooooooth too. Highly recommended.
