Wheel Spacer Question

[ADCD875]

Below is a steel wheel (for Mini) to be used to mount winter tires.

Size: 16" x 5.5", 4 Lug, 100mm Bolt Pattern, 45mm Offset.

What size spacers do I need? I will be mounting these on my 1991 318is.


Thanks

A 15mm would do the job, a 20mm would look best.

Double check the center bore of the wheel, I think the Mini wheels are smaller than 57.1.
