If there's a tire on the rim, read the numbers off of it. – Daniel R Hicks Nov 27 '14 at 14:15 — Daniel R Hicks, Nov 27 '14 at 14:15

Measure the diameter of the bead seat (i.e. the place where the tire bead will sit). It will most likely be one of these:

The new tire will have a marking on it like 28-622. That second number is the diameter.

Also 650b (584 mm) is making a comeback. – Rider_X Nov 26 '14 at 22:39
28-622 the first number is the width in mm! – Carel Nov 27 '14 at 08:40
But note that the tire width is greater than the rim width. – Daniel R Hicks Nov 27 '14 at 14:16
