This is the same wheel/tire size combo I'm leaning toward. I was planning on Conti DWS 245/45/20s all around, with either OEM or replica 214s on the rear to replace the factory 315mm style 214s I have now.

Did you use spacers on the rear wheels? I've read several posts where people suggested 25mm spacers if using the narrower front wheels on the rear of the X5 e70. I notice you don't have fender flares installed, so maybe it wasn't needed... are the spacers purely cosmetic?

Thanks,
Nathan
