I have a set of replica 220M wheels in a square 18X8 setup wrapped in 225/40/18 Michelin X-ice tires with plenty of tread left.
Price: $850, local pickup
I bought this setup from a previous M3 owner last year and had them installed for a few months and decided to store the car for the winter.
Pics below (sorry for the crappy pics):
Thanks for looking!
