Nice, assume you're happy with the Hankooks so far?
I've been running staggered winters on my 325i (225 front, 255 rear)for the past 3 years and it has been fine aside from getting stuck once in the alley behind my house last year. I chalked that up to the deep iced over tire tracks and not the performance of the winters though. Hopefully the 235/265 setup on my M3 will do the same... fingers crossed we get less snow this year than last!
