WOW! Scary stuff JR. Glad you are okay. But sorry you are going to incur a repair bill and the inconvenience of no wheels for a spell.
Reminds me about 20 years ago I was driving down the highway in my jeep with the top off. Out of no-where this big truck tire - wheel and all came bouncing over the jersey barrier. It hit about 30 feet in front of me and bounced and I drove under it doing about 60 mph. I doubt I would have survived a direct hit. It looked almost 4' in diameter. I just hope I still have enough lives left to make it through the next 40 years.
