I'd be willing to bet that something at some point has hit it and weakened it or something. Crazy either way though.
How did he discover that it had happened? Did he hear it? I can't imagine he randomly decided to check it.
Ummm, you should have pulled over to take off one of your wheels to replace it....:shrug:
My thoughts exactly! I hope he did this
Do what now?
Why would I replace the spare with a good wheel, then use a blown spare? :dw:
