I'm still not sure.  I hadn't considered the possibility that the

In long ago discussions in this forum, there was mention of the problem
of pneumatic tires on museum bicycles deflating over time. Supposedly,
one solution is to "inflate" them with water instead of air.

That works if the tube doesn't also leak water.  For vintage wheels,
the rim and spokes will likely be steel, which will eventually rust.
The water might also leak.  I don't think the museum would tolerate a
water puddle under each tire.  Methinks soft expanding urethane foam
would be a suitable leak and rust proof alternative to water:

The result is a closed cell foam sponge that might possibly be
rideable.  I've never tried it.
