Are you having trouble on ice? If you're having such trouble pulling away on level ground, it sounds like snow covered ice. Go for something like the Blizzak, Nokian Hakka Q, or Hakka 1-studded.
I've got Pilot Alpin's on the C230, and they're great on dry pavement, pretty decent in the snow, but lousy on ice.
