So, common knowledge that properly inflated tires give you better mileage.

Why is that? Less rolling resistance?
(The random things I think of when I'm driving to pick up lunch...)
I never looked it up, but I would assume when a tire is under inflated it has a flat spot on whichever part is touching the road, and each time the tire moves it has to squash the sidewalls as it rolls. It probably takes more power to move.
