Seeing the question from AARCuda340+6 made me think about this one. I have to keep a spare in the trunk (German law), but I can't mount it or anything (all the brackets are gone). I also don't keep a jack or lug wrench. The spare I have is really just for show (it is a 15X3 skinny front). It will fit on the front since it is the same size, but no chance on the rear. My plan is to just park and wait for ADAC (like AAA) to show up and tow me.
