From your id, your probably have the ruby black w/oyster....
I had the exact same setup you are contemplating on my '10 335i. My tires were Continental ExtremeContact DW - they have a slightly rounder sidewall profile and they fit just great. See here:
Keep in mind that not all 275s are created equal. A tire with a more square sidewall profile (like Bridgestone RE-11 or Michelin PSS) will be different, but I don't think you will have problems.
