Ohhhhhhh, tires...... I really like the Michelin Energy Plus on my new TDI. Pretty quiet and stick to the road pretty well, very good handling. They also have a very low rolling resistance (better mileage). I am quite sure you could get tires that stick as well but not as low rolling resistance for much cheaper though.
For stud less snows you can't touch a Nokian Hakka Q's. Talk about stick! But they aren't exactly quiet. The place I got them from actually had an old Mazda 323 with a snow plow on it, with 4 Hakka Q's. They said it was great for smaller driveways and they haven't got it stuck yet! I suppose the extra weight of the plow on the front end, with front wheel drive.
Anyway I would recommend looking around tirerack.com and … darn I can't think of it right now, the other big one. Anyway lots of good info on both sites.
