Hi all,
I'm looking for some winter rims for my 2017 M2

On papers (we have very strict rules here in Italy ) I'm bound to:

square setup: 235/40 R18 (no J or ET specified)
or
staggered setup: 235/40 R18 8.5J ET27 + 255/35 R18 9J ET29


I was looking for BBS CH-R but no luck with ET in 18" size. The only alternative seems to be the original M640 18" setup from BMW, have you any hint?

APEX EC-7 in 18" clear the brakes I believe.

thanks, unfortunately closest fit is 8.5J R18 ET35... I think it doesnt fit or looks very ugly

doesnt have any 18" in configurator for M2 and I'm in Italy, shipments costs will be a no-go.

I run oem 640m for winter set but another oem option that works is
E92 m3 oem 18" wheel (270m - see attached photos - 8" width et 20mm) - you could run either all round 235 or 245 F&R or staggered 235/245

thank you, this is a viable alternative solution

Also looking at winter setups. Would 235/45/18 be better than 235/40/18 because the diameter exactly the same as the stock rear wheels 265/35/19's diameter? Also it has a +1.9% diameter difference compare to a -1.6% for the 40, so not a huge difference.
