To answer those that asked, there are (4) reasons why I am concerned:
1. I've come across many on-line references tables that indicate 14mm rim width and 32mm (1¼ inch) are not really compatible. In fact,
https://www.betterbybicycle.com/2014...of-wheels.html states "The ideal relationship between tyre and rim section is about 1.8 times, but any tyre from 1.4 to 2.2 times should fit – always provided that the bead diameters correspond." The calculates out to 19.6 to 30.8mm tire for a 14mm rim.
2. Knowing a lot about automotive tire sizing, the accepted ratio even for narrower tires & rims (e.g. 5 inch rims) is in the range of 1.22 to 1.44. Even the vintage VW beetle, a car noted for narrow tires or (for the day) large diameter rims had a tire to rim width ratio of 1.4. ......Yes, yes, I know car tires and bike tires are different animals.
3. I tried a 27 x 1.25 tire on one of these rims. Admittedly not a very good tire, but the tire was labeled 85 psi max. When inflating to anything over 70 psi, the tire bead separated from the rim and popped the tube.
4. My other bike that uses 27 x 1.25 tires has 19mm rim inner width.
