I just got my 5, and man that thing is useless in the snow. I drove my Miata year-round since it was new (91) with snow tires and it was fine. Of course I never had to shell out for 17" tires before, so it will be a while before I can get a set. So, what snow tires have you guys run on your 5's? I've had Nokians, Blizzaks, and "Winterforce" brands on the Miata so I have experience with several types.
