Further update. The patch on my 584x48 has held nicely, though I haven't ridden it yet. Meanwhile, the rear tire on my ST-22 (622x32) turned up flat yesterday. I took the opportunity to take out my Riv Road (622x32) and enjoyed a very fast (for me) ride. This evening I pulled the tube from the ST-22 and found a tiny hole. Exactly like the 584x48, I found a tiny bit of wire in the outer tread but not apparently poking through the inner casing. I patched and replaced the tube without incident. Alcohol wipe and Park glueless (MacOS still wants that to be clueless) patch, applied with the tube inflated.
The fact that I've easily removed, patched, and reinstalled a couple of tubes strengthens my belief that the tubes that failed on installation were probably defective. It also gives me a bit more confidence in the tubes (and my ability to repair in the field) going forward. They sure feel good when riding. No word from RH on whether they're going to refund/replace the tubes I returned to them.
