Really? You can't imagine any? Regardless of how unlikely it might be, there's a very real risk that shit's gonna go down in the next week and who knows what might happen. Even if nothing does happen, there's been an increasing amount of unrest in the past few years, it doesn't hurt to be prepared for the worst. You probably won't ever need to use the spare tire in your trunk, but it's reassuring to know that it's there if ever you need it.
