Oh my. I built a new wheel using a tubeless ready rim. I used a tubed tire, which was a bit hard to install, but I didn't think much of it. Never flatted it - yet. I'm taking that tire off tomorrow and remounting it, just to see! And maybe we need to use only tubeless on tubeless-ready rims, like it or not. I'll know tomorrow.
I don't know the answer to the OP's question. Problem is that tire models change over the years. I have some old tires that were easy to mount, but they aren't made anymore. I always tried to use rims which had deep wells. This tubeless business is a new hassle in our lives. The rim I used isn't available in a tubed version.
