Drive mine all year round -- 3 winters so far with no problems at all but had a good set of winters installed. I went with the Goodyear Eagle Ultra grip GW-2's -- they are fine in the snow and ice- not as good as Blizzak or other Ice tires -- but way better in the dry and wet -- in fact you have a hard time feeling that you are on winters, they do not have the dry grip of the summers but have a much better feel than the Pirelli winter 210's which IMHO feel like mush in the dry. Other good High Performance winter tires are the Dunlop W2-orW3's [some thing like that] or the Blizzak LM-22's --These tires are full winters but built with a high performance bias which make them more palatable for 'Spirited' drivers.
I think that that Goodyear has a new version out this year --GW-3 but have no experiance with these.
