Eric Do you have other tubeless-compatible wheelsets? Among your 2, 3, 6 tubeless compatible wheelsets, are your A-23s unusually or uniquely different from all the other tubeless compatible wheelsets in your stable?
Technique-wise, the key is pushing the bead into the deep well in the middle of the rim. If the bead is down in that well, then it's loose. If the bead is up on the shelf of that well, then it's tight. That's it. Hand a good mechanic one of your wheels and tell him to take off and re-install your tire. If the mechanic curses, it's the rim. If you are amazed at how easy a mechanic can make it look, try to learn from them. This is a good situation to bring a six-pack. Here's another suggestion. Take the tire and tube completely off. Set the tube aside. Put one bead of the tire on the rim, being careful to have the bead down in the well. It should be totally easy. Pull the tire back off the rim with your hands. That also should be totally easy. This is what it feels like to get one bead on or off the rim when you've pushed the bead down into that well. Get good at that. That's how it should be for the other bead. If you can't get good at that, your rim is oversized. When you go to push the other bead on, the tube may get in your way and might make it more work to push the other bead down into the well. Do it anyway, work that second bead down into that well, so it's loose and easy to install.
