These are the wheels that come stock with the LSE (limited sport edition) versions of the hatch and sportshatch E87 in Europe. Only the LSE was available in Carbonschwarz and I believe 2000 of them were made.
Front: 7,5x18 215/45R18
Rear: 8x18 225/40R18
They also come on the E90 LSE but in different sizes. I think they're also available in the 135i stock wheel sizes (so a 8,5 rear)
