Vice-versa, if you have rims without hooks, the wire bead seat in the bottom corner of the rim inner face is usually very well engineered to hold the tire in when atr pressure is added. I believe it’s essential to use those two together, and not to mix and match the two types of tire mount system.
It isn’t worth the risk to run a mismatch, and these two old systems both work extremely well, when installed properly.
There is also the issue of difficulty in installation and removal, which curses me frequently when using modern tires on older rims. (All of my rims except the Arraya rear on my UO-8 have beads, so that is not the issue here.)
