I have a 2013 X1 3.5i that came with 8" wide Style 322 Y-spoke wheels all around (BMW part #36116789145). I also see that there's a Style 322 Y-Spoke that is 9" wide (BMW #36116789146). So my question is: can I replace my 8" Style 322 wheels with the 9" version? I am guessing the 9" Style 322 will only fit in the rear and not in the front, so I can only replace the rear wheels. But maybe you guys know better and can let me know if all the wheels can be replaced with the 9" Style 322. Thanks.
