It's dark, snowing, raining, family in the car, full of stuff. How do you get the spare tire out or lowered? You just hit a pot hole, instant flat no tire pressure warning either. Where are all the tools, jack, lug nut lock? Has the pressure ever been checked. And in the case of GM suv's and trucks there is a safety catch in case of a cable break. You will not be able to lower the spare because the latch has corroded and no matter what you are screwed by the side of the road. It needs to be lowered and lubed every year or two. Even without that issue, practice, practice and check in the garage, not stuck out in the middle of nowhere with a dead cell phone battery. A 12 volt air pump might help, but with all the pot holes that probably won't bail you out because you put a 1 in. hole it the sidewall.
