Ahh, on Bimmerfest, OP did not mention he has third row. When car is equipped with third row, you can't order space saver spare since there isn't room to put it. So you'll have to order it aftermarket and put it behind in the third row or like the picture above, fold down third row and put it in the trunk. I think most, if not all cars coming out of the SC factory will be factory equipped with run flats so the owner has to opt into ordering space saver spare, if available.
