Pull a wheel and inspect the back side. It will show the width, diameter, and offset. You may have to look a bit harder to find the country of origin, manufacturer, and date of manufacture. If it is a OEM BMW wheel, it will have "BMW" somewhere and a part number.

IIRC, modern BMW wheels come in just 2 bore sizes. So, if it is an OEM wheel from another series, then it is the larger 74.1 size mentioned previously.

If it is an aftermarket wheel that the BMW center cap just happened to fit, calipers will be needed to determine the bore size. (Clean the bore before measuring.)
