is there a bunch of tire "dust" stuck in there still?
It's possible, I certainly didn't look at that specific tire before she left Tuesday morning. A bit weird that it would so much less inflated than the other tires, but if there was a slight leak I suppose it could happen.

There was tons of black powder on the inside of the tire. What does that mean?
