What 'donut spare tire'-fits the R60 Countryman- to use as a spare?

Says it fits...

 

I suspect the hatch will not close with the spare lying like that. Also, you lose the use of the trunk. Would have been nice if it could go below the floor of the trunk. My MINI is not handy right now for me to see if this is even possible ... I suspect not.

 

Pull the handle and slide the rear seat forward. That may create enough room for the spare to lie flat.
