Anything flush/poke will require a roll unless youre 4x4. I hope you listed your tire specs wrong. It should be a 265.30, a 9.5 +28-30 would be max flush without a roll and true flush on a e92 is impossible due to the .4in thick quarter panel which is impossible to roll flat. Shaving it flat while trying to fit a 9.5 265.30 is a waste of effort.
btw....Alen E90 is the e90post angel, just sayin:
