I just took these off my CPO 2006 330 which I got a couple of weeks ago.
The rims are staggered, fronts are 18x8 and rears are 18x8.5. They are very clean -- no curb rash, dents or dings.
The tires are Bridgestone Potenza REO50A runflats, fronts 225/40R18 and rears 255/35R18.
From what I understand, new treadlife is 10/32nds. All tires have somewhere between 9/32 and 10/32nds of tread as measured with a double square.
I'm in Washington, D.C., and I'd prefer to do a local sale, but will consider shipping if I can't sell them locally.
You can PM me, but I'll probably respond faster to email: joel dot vengrin at gmail dot com.
Price $1,200 (plus shipping if required).
