Those w/214s
 

Could you please go check and see if your rims (particularly the rears) fit completely flush with the hub plate?

I just had my dealer swap out my winters and bolt on my OEM 214s, but I noticed both rears (and fronts to a lesser degree) have approximately 2-3mm of a gap/spacing around. Driving home at highway speeds, I did not notice any vibration or anything unusual. It was just when I was wiping the rims down that I noticed they were not completely flush.
Thanks

So this morning I went to the dealer to checkout other X5s on the lot w/214s, and sure enough, those with 214s were not completely flush with the hub.

Sorry for the very, very poor pics, but it looks like the small spacing around is "normal." Even the Xs with M-Sport 20s" were not completely flush.

this is normal design, verified I have the same, and I just had my 214s installed (myself) too.

Thanks for checking Alex.

Here are a couple "better" pics from the Xs on the dealer's lot.

actually what appear as a gap is due to radius on external corner. Wheels fit flash to a wheel hub.
