Except that he doesn't do any miles on them with tubes - just fits them, inflates the tyre till it locks to the rim, deflates, unhooks one side, removes tube, refits the side, add sealant, amd inflates. Seems to think it always works.

My limited experience suggests that a folding tyre needs time on the rim with a tube in order to get rid of the kinks in the sidewall where the tyre had been folded . A gap of a few mm caused by one of these kinks will let the air out faster than it can be blown in. Warmth and sunshine might help in this process which, in my case, are better obtained when the bike is outside (depending on the weather) than being in the garage. I had found that one 27 mile ride wasn't enough to get the tyre into shape but it seated OK after another three rides.
I've often had one side of a tyre seated on the rim but there's a gap on the other side too big for my inflation system to overcome. I suspect that some tyre - rim combinations work better than others.

Yes I agree. I had to replace a tyre and could not get the new one to seat properly despite having one of those pumps with a high pressure chamber. After several fruitless attempts and much swearing I put a tube in. I left it on for a couple of days but didn’t ride on it. I then carefully removed the tube through one bead with the wheel horizontal across a bucket, I put the valve in and fitted the bead. It inflated first time. I then removed the valve core and added sealant, reinflated and all has been well.

Thanks John and Geocycle good info for when I'm due for new rubber.

If you want to go down a rabbit hole on tires, here is a 13 minute video on what is the best tire for the Great Divide. All kinds of weird tread patterns, different casings, all tubeless of course.
The final answer is Rene Herse (compass) Fleecer Ridge. Just so you know.
