I'm updating the 18x8 square setup on my xdrive to 19's, (19x8.5 ET35 & 19x9.5 ET40). I understand that the diameters need to be within 1%, and I'd like to stay within BMW's OE parameters since I'm still going to be under warranty. I'm finding a few different setups that should fit within this requirement:

245/40/19 front & 275/35/19 rear
235/40/19 front & 265/35/19 rear
225/40/19 front & 255/35/19 rear
or a maybe a 255/35/19 square setup

I've read in some posts that BMW put 19's and 20's on the xdrive's from the factory, but what I can't seem to find is what tire sizes BMW put on the xdrive's with 19's from the factory???

Anybody have the #'s on this?....or any other input is appreciated!

225/40/19 front & 255/35/19 rear is standard on 8x19 front 8,5x19 rear

Thanks, that's what I'm going with.

I REALLY wanted to go with the 235/40/19 front & 265/35/19 rear to fill the "gap", but finding a brand match for front and rear in all-season wasn't happening. Also, since it's a new car I decided it was best not to give BMW any reason to void any part of the warranty.
