I received several off list postings from people who had used such a combo with good luck. Thank you

The Michelin Dynamics have steel beads and I intend to run them near the middle of their 58-87 psi range. It's nice to see that it's becoming more common to find tires that give a range of pressures instead of just a maximum. And tires that are actually as big as their nominal size. I like a tire that is large and supple enough to roll well at moderate pressures.

Before riding I'll pump them up to 125 or so and let them sit overnight. Rims and tires have a +/- tolerance and judging from the chore it was getting the old tires off, I think these rims are on the plus side of the tolerance.

Right now I do have a 20 y/o set of folding 23mm Michelins on them to protect the rims as I build up the bike. They seem to be seated well into the rim.
