Been doing great with these all terrains on black ice all season until now.
All-season (all-terrain) tires are in no way, shape, or form suitable for winter driving. Even in dry conditions, the rubber compound in an all-season tire is designed to perform at temperatures over 7°C.
There are three types of tires suitable for use in winter:
1. Winter (in some places called "snow") tires, which carry the severe weather rating symbol.
2. Studded winter tires, which carry the severe weather rating symbol (but which are not legal in all jurisdictions for use on public roads).
3. Newer on the market, "all-weather" tires (NOT all-seasons), which carry the severe weather rating symbol. These aren't very common, but are made by manufacturers such as Nokian (I have a set of their WRG2s on one of my vehicles and love them).
Notice a trend - the severe weather rating symbol. In Canada, it's a little snowflake inside a mountain, and will be stamped on the sidewall of the tire.
And were it me, I'd be having a shop check the integrity of the frame after rolling (even a gentle roll). Struts are generally designed to take one roll event and prevent the car from crushing itself - you're putting yourself at risk of the roof collapsing entirely and crushing you if there's ever a next time.
