As a general concept and keeping it simple.

The idea is the circumference of the tires and wheel combinations are all the same (or very close) for our 5'ers. Larger rim size means less tire sidewall height. Less sidewall height would be quicker steering and handling inputs BUT less cushion or give, in response to poor road surface.
