It depends on what you mean by width. If you view the wheel as a disk and consider its width as the side-to-side measure, then they two are the same so the ratio is 1. If you view the wheel head-on and consider its width as the profile, then there is no relation.
Yes, at about a pinky fingers width.
About the width of Aubrey Gibson's head or 4 feet

The head or the point of the pin? I would measure the head in millimeters and the point of the pin in micrometers.
Do-it-in-your-head method:Length + width is half the perimeter, ie 76 inches;76 - 36 = 40;Half of 40 is 20: this is the width;20 + 36 = 56: this is the length.Job done.
Do-it-in-your-head method: Length + width equals half the perimeter, ie 106; 106 - 8 = 98; half of 98 is 49 which is the width, making the length 57.
Do-it-in-your-head method: Length plus width is half the perimeter ie 161 cm, of which 68 is width so the length is 93 cm.
