No signs the 32-630 (27x1-1/4) tire is
making a comeback?

LOL. No, but a 27.5" tire is only
a little bigger.

These tires are virtually identical in applied
height - using a folding ruler, and leaving the
wheels mounted on the bike, both are about
27-1/2" or 70cm.

This is one example where the English system is
handy, and the ISO can be confusing.
