I bought my 2016 Countryman used, not realizing at the time there was no spare. I discovered this (fortunately not in a time of need) shortly after putting on four new Michelin CrossClimate-2, so I was certainly not going to switch to run-flats. And like you, I want a spare. Always. The only reasonable solution I could find was a tire/tyre carrier as shown in the picture. It's made and sold by M7Speed (M7Speed.com) and cost me about $1,000. Not cheap and even less the case if shipped to a place where you use petrol. On the positive side, it installs easily in the threaded rear tow hook receivers and it swings nicely out of the way for lifting the hatch. No holes to drill and no mods to the car. Does not block either the plate or the rear window to any extent that matters. Money well spent for someone who loves the car but must have a spare.

As a tire carrier, this thing is 100% solid. The problem with this is that they clearly never thought to test this rig on a model with reverse sensors. The rig completely blocks the middle two reverse sensors, rendering them useless. Whenever you go in reverse, the car will scream at you because it thinks you're about to hit something. The solution I was given by M7 was to either live with it, disconnect my sensors, or return it... How do you miss something this big?
