My Sonic made it through it's first Michigan winter just fine. Only slipped around a few times during the really heavy snow fall. (Considering Michigan had a fairly tame winter this year)
We got 8" in Chicago.. Made it 1/4 through a turn into a parking lot at 10 mph and slid into a curb at 10 mph. Cracked the rim and bent the lower control arm. It's a cheap fix but the damn control arm isn't available for a month !!!! Starting to think this car is full of bs
Haven't got caught out with it during a snow so cannot comment on that. Have winter tires on the EVO's stock wheels (General Altimax) and have the Forester as well with newish All-Season Bridgstones'
So unless I get caught with it somewhere in a storm I'll likely never find out.
