There is a reason that the official package offered by BMW is staggered. I don't know why people buy an expensive M2 and then cheap out by getting a square setup for rotating.

Like in warm weather even the non comp M2 struggles on 265 rears. A 235 rear winter tire seems basically insane IMO for dry cold weather driving. Plus it looks ridiculous unless you run spacers. And running spacers isn't that desirable in crap conditions.
