Are BMW wheels stamped wih sizes?
I picked up 4 307 style wheels that came off a 2013 X3. They have to be 18" because I'm sure they are not 19" and I don't believe that the X3's came with 17" wheels. You would think there would be something stamped on each wheel but I can't see it. Maybe it's in the back of one of the spokes but it's too dirty and can't see the metal. They sure as hell look like 307's so I'm not too concerned. Anyone know if the size's are stamped inside or some sort of designation?
