My wife had a blow out on the Interstate in her Highlander SUV a couple years ago and the tire had a pretty big cut in it through the thread. She said she didn't remember hitting anything and thought it just blew out. I took it down to the tire shop to have a new tire put on it and after they removed the damaged one they called me into the shop to see the wheel. Apparently she did run over something and it not only sliced open the tire but put a nice ding to the inside of the rim. It wasn't really an issue where it was and didn't reflect through to the outside so the wheel is still on the car. But it's possible that sometime in it's life something similar happened to that tire/wheel and put a bigger ding in it that did reflect through.
