Bob here.
What was left of the tire was spread out all over I-70. The core of the tire was still there but nothing of the sidewalls or tread. I was not going to go out into traffic to try to find parts of the tire to do an autopsy. I checked her other tire and it was at 50 psi just like it said on the sidewall. I did not look to see what brand or country of origin the other tire was.
I did not want to ruin her day and explain to her that she was probably out of luck as far as the dealer backing anything but MAYBE a new tire and rim. I have no idea if she had insurance or not. Unless she can find a handyman, she may find that repairs will exceed the value of the camper.
