They don't. Also, ever since I switched to thick tubes it
takes 6-8 weeks to drop to 75psi.

I can't remember rolling a tire off unless the pressure was
reduced to near nothing by a flat. I'm sure that you could roll a
tubular off at lower pressures so that might be where that myth
came from.


I only know it from mountain bikers running low pressures on
tubeless tires ... PSHOOOF ... sometimes a wee bit of air remained,
sometimes it was all gone or the tire came off.

Of course, the real die-hards will not be fazed by a tire coming
off:

I have only done that slowly and as straight as possible. When a
side wall blows out the tube and tire are hosed anyhow so I
continue riding on the flat as long as possible. Pretty much until
the tire is about to wear through where the rim could contact the
soil or pavement. Any mile not walked is time saved for the trip
home.

I got a flat on a gatorskin and discovered my flat pack missing. I
don't know if it fell off or was stolen.


No, no, you sent them to me :-)


... There was a Performance
Bicycle in Dublin that I remembered and rode three or four miles
there and replaced the tube etc. and carried on without any visible
damage to the sidewalls of the gatorskin.


Then you were lucky. Mine were unfixable, it looks like someone fired a
45 through it from the other side.
