If there's a tire on the rim, read the numbers off of it.– Daniel R HicksCommented Nov 27, 2014 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:
- 559mm = MTB 26 inch tire.
- 622mm = 700C (a.k.a 29er)
- 630mm = 27 inch that is old enough to remember the Bee Gees.
If it's not one of those, look it up here: http://sheldonbrown.com/tire-sizing.html#iso
The new tire will have a marking on it like 28-622. That second number is the diameter.

But note that the tire width is greater than the rim width. Commented Nov 27, 2014 at 14:16
