Go to the Tire Rack web site and read reports on the tires others have used. You can find reports specific to your exact chassis. I found it very good info. The 210 chassis just seems to eat tires. I ended up buying Bridgestone Potenza RE950's. Jury is still out on their longevity, but Toyos and Michelins did not give me the mileage I wanted.
I'm pretty happy with my Blizzaks. They've worn well and weren't terribly expensive. I didn't drive the car much last year and just left them on thru the summer. Of course they're noisier than 'regular' tires. Winter traction is decent, but even with 4Matic it's no substitute for a 4 wheel drive vehicle. (I drive a 4x4 if there's more than 4" or 5" of snow.)
