Continental Tires
I drove this car with the Continental tires in Michigan winter conditions with little difficulty. (You probably get more snow than we do in Ohio.) Most of the snow we get here turns into that nasty glazing that comes from the tires of the traffic melting and refreezing the stuff into ice. I got around fine in all of it. The couple of times we had deeper snow had me feathering the throttle, but again, I felt comfortable. The Michelins, however, will not even move the car in the lightest of snow, especially with an automatic. (The idle torque alone will break the wheels loose and then there is no go at all...) If it said snow in the forecast, I couldn't take it out of my driveway.
I've talked to a number of people though that are buying a second set of winter wheels with winter tires. This is what they do in Europe every year. (They don't have all season tires there.)
