Got miles before me, miles behind
I am fine. The car is fine. The right front tire which blew out so hard that I thought someone had hit me because of how violently the car lurched sideways is not fine; it is in the trunk with a considerable chunk missing. The spare tire previously in the trunk was changed on for me by a reassuringly matter-of-fact mechanic at the Gulf station I was able to pull into, whom I thanked because it seemed really stupid to have to call AAA from a gas station. There was no obvious etiology such as a dire pothole or a bolt in the leftover rubber. I have been in cars whose tires were losing air before, but never one where it just exploded. Could do without repeating the experience. It did not rise to the level of my parents' experience in Philly, where three of their tires detonated in quick succession on the highway in what later turned out to be some kind of manufacturing scandal. I did not hit any of the cars around me, which I really was worried about.

Thank you!
On inspection of the exploded tire, my father thinks it had suffered a previous injury from being parked too hard into a curb and blew up along the fault line, to mix several metaphors. If so, we have no idea when it would have happened; my problem with curbs is that I am normally too far out from them and more specifically can't remember even worrying about running into one prior to the blowout. It is a thing to keep an eye on in future.
