If you can see the canvas, you've got about a thousand miles left in 'em.

Rather than having a tyre maker tell you there was one millimetre left, you looked for yourself.

Something about seeing the Queen's head = replacement time (1mm is the distance from the edge of the coin to the crown) or something along those lines.
