My GF just bought a 2015 428i coupe with 17" rims. I was wondering if I can put my 2014 550i M wheels on it.

9.0 x 19 (ET) IS44 with 275/35

Bolt pattern and center bore (hub) need to be the same, mainly the bolt pattern, you can always adjust for a center bore that's smaller. As long as that checks out, this should work.

Put them on and they look and fit great.
