Also makes a big difference in the size and shape of the tire. The wider the internal part of the rim, the wider the tire and the higher the profile. That seemed counter intuitive to me until I looked at it and realized that the wider the rim, that rubber on the sidewall part of the circumference now goes into tire shape instead of tucking back into completing the circumference.

Matters if you're trying to get a bigger tire on a road racing frame that "accepts" up to 28mm. Maybe yes, maybe no.
