I"ve had a lot of luck with Michelin X-ice and in the past I had their Pilot Alpin's on my 240sx I used to own. Both excellent!
IMO, I'm from Ontario originally and winter tires out there are essential. Here... not so much so.. unless we get freakish weather like the snow storm we had 2 years back. Last year though, my snows were useless, it hardly snowed at all, except when I'd go boarding.
