Hi,
I am interested in finding out what size of wheel was fitted to the John Cooper conversion Minis in the late 80s, before Rover had made the 4.5x12 wheel for the Mini 30. In the photos they fill the arches much better than the Rover wheels. I have a reason to suspect they could be 5.5 x 12 but would love someone to point me at some period information about this.
Thanks,
- Rob
