On Tuesday, July 21 around 6:05 PM, I was driving northbound on the 405, close to the San Gabriel River crossing and about half a mile before the Palo Verde Ave exit, when a large truck tire came across the lanes and struck my car (a white Porsche Macan) broadside. The tire kept rolling and continued down the freeway afterward.
Traffic was heavy, so many drivers likely saw it or caught it on dashcam — especially anyone who saw where the tire came from or the vehicle that lost it.
If you saw it happen, have it on dashcam, know where the tire ended up, called 911 about it, or can confirm it with the police, please reach out via DM. Also, if you know of another incident nearby around that time that might be related — a truck losing a tire, another car hit, debris reported — please let me know. Even a partial detail would help enormously. Thank you.
