I don't know. Like @frahm30 (sorry, don't know your actual name) said, I think rider weight might have a lot to do with it. I had RTPs on my All Rounder, using 17mm rims, and absolutely hated it. I moved them over to an old mountain bike with wider rims and they're great. On the narrow rims, I had to pump them up so high to avoid squirming while cornering that it felt like I was riding on a pair of basketballs. Bouncing down the road. Before 2.6 and 2.8 tires were a thing, I settled on 2.4 Ardents on Velocity Dually rims as my mtb tire of choice, because I liked what the over-size rim did for them. I could air them down as far as I wanted, without worry about rolling a tire off the rim. (This is where I do appreciate tubeless, because I'd get pinch flats otherwise.) Part of my preferences might be influenced by my huge fear of rolling tires though. Any squirm or collapsing of the sidewall send shudders through me and makes me ride tentatively. I've rolled tires right off the rim a couple of times, and have never recovered physically from one of the resultant accidents.
