Wheel sizes for Rover Mini Mark VII

[hutten]

I am looking at new wheels tires for my 1997 Rover Mini. It has 12 x4.5 alloy wheels from the factory. Has anyone gone to wider 5 inch wheel on a similar Rover Mini MPI car?

Will going to 5x12 wheel with Yok A539 165/60/12 tires require a spacer?
Thanks Rich

Got my answer from Mini Sport in the U.K. The 5x12 inch wheels will fit without spacers or modification.
