I have never been a fan of the 30+mm spacers as they change your wheel mounting mechanism from bolts to lugnuts which kind of looks strange.
Also the nuts don't have the shim like the bolts which prevents the wheel to be scratched in the mounting area(s).
I for myself decided to go with
powdercoated black OEM wheels for the no-snow winter days and for the few days with snow on the road I have a set of OEM winter wheels/tires. But than again I have a tire place across the road where I can store my wheels and can have them changed in Formula 1 pit stop style (call 5 minutes ahead and I am out in 15 minutes)
