Whew!

Well, I took the car by the tire place today... And was told that the tire actually had no damage at all, that what looked like a little scrape with some bits of rubber shredding off was actually just peeling glue. But the guy applauded my conscientiousness in checking. Why there was glue on my tire, I do not know, but I am not sure I have it in me to care. As long as I can avoid a repeat of last night's car-related anxiety dreams, in which, among other not-very-fun things, all kinds of bizarre dashboard warning lights I'd never seen before were coming on, and AAA still hadn't shown up three hours after I called them.
