Overinflation is just as bad, but I don't know how overinflated tires
fail because I have not really seen any of those. Underinflation is much
more common.

Overinflation also puts undue stress on the sidewall, but not in the same
way.

He's likely right. See any dry-rot cracks on the other tires? See any
sidewall damage anywhere?

So she's a person who is prone to running over nails frequently?
