Ah, now this type of Pino Morroni wheel, I have photos of! The basic idea (don't shoot me if I'm way off here) is that when under weight load, a wheel will compress or ovalize just a bit as it is turning, and that in that moment, the spoke in the "flattest" section of the oval sides will be momentarily left loose, and able to lose true. In addition, an oval wheel is not as fast or smooth as a round one. In this way of nutting on both sides of the rim, the wheel cannot come out of round. Something like that anyway.
I think the tire was specially made to fit the unusual rim contact area, but
I can't recall for sure ... still working on putting together notes, and they
are not in front of me. When the crude photos were taken, I tried to pull
back the tire to show the underside, but it was on too tight!!! It is however,
very easy to see the nuts on both ends of the spokes, but the nuts inside the
wheel cannot be seen ... just a recess that one of the nuts sits in:

The one end threaded into the hub flange and the other had what appeared to be spoke nipples threaded inside and out. The nipples had a lock nut that pressed against the outside of the rim. Hope I got that right. I'm dealing with 25 year old memories. Behringer had a pair hanging in his shop. Must have been a bugger to true.
On an aside I doubt that the red Pino bike is a Titanium Pin-Behr. Cecil always said when they vacu-brazed the frames they back filled the furnace with Nitrogen. It gave the Titanium a surface layer of Titanium Nitride. (The same stuff found on premium drill bits). This made the bikes a gold color. A real bugger to get paint to stick to it. He also preferred 3-2.5 Titanium. It was easier to braze.
