Great writeup save for one
slight detail:
You will want to put the nuts on with the beveled side inwards, so they push into the metal of the spare. Otherwise, there will be a slight amount of space regardless of how tight it's screwed on and the wobbeling of the road will loosen the nuts. At the extreme, this can cause the tire to come off and your car to spin, potentially messing up your seven dollar haircut quite severely.
