Here's a list of a lot of tires, each link brings you to a review where both the measured width, as well as height are provided. Good luck finding very many where they're the same and the width isn't in fact measurably wider.

The tires height is measured from the bead. Not from the bottom of the rim. If you complete the circle that the tire is forming then the circle will be closed pretty much at the bead.
