I am considering buying a new set of rims for my E90 LCI xDrive. I have a set in mind that is 19x8.5 ET35 in the front and 19x10 ET38 in the rear. I was just wondering if these rims will fit without rubbing and what tire sizes I should be running? I know I have to worry about something with a 1% difference because I have xDrive but I have never fully understood this. Any help would be great!

Yes those will fit. You most likely can get away without rubbing, if not then only need little bit of rolling at rear.

Tyres 235/35/19 front and 265/30/19 rear. These have 0.8% diameter difference, if you want you can use 225/35/19 at front then difference will be 0.2%. Basically use that calculator on top of the page. Put your front and rear tyre size there and compute. It will tell you the diameter difference. Closer to 0% means that tyres are almost "same" size and for xdrive the goal is to keep it under 1%.

This is E90 pre-lci with 19x10 et28 and 265/30/19. No rubbing. http://www.e90post.com/forums/showthread.php?t=816527 The 19x10 et38 on LCI extend to same point as 19x10 et30 would on Pre-lci E90, because the rear track difference.

Ok awesome. Thanks for explaining all of that.

Just another tire question, will running a 275/30 give me any rubbing issues?
