I have tried it and it was a flop because the inner tube that was used was
not stretchy at all points (thicker rubber) and the measurements taken were
the average of both the small and the large sides. Plus the soldered brass
pie shape wedges that took the shape would not flex. I learned from it
though. The whole thing was lopsided and even with the air pressure to make
it fill up more on the other side would break the solder bonds regardless.
Get those aluminum trash bins sold for airports. Look at them online, buy
two tops and fit them together, project done.

I recently had the two front tires swapped out in preparation for the
impending winter, and was told that one of the old tires had too much wear for
next spring.
Then it dawned on me - a car tire is basically a toroid! I drive a simple
Toyota Corolla so they are small/average size, weight is really not that
much of an issue for the 4" diameter coil form I have.
Has anyone tried using a car tire with maybe a couple wooden discs to make
a closed area, then covering the whole thing with AL tape?If you have,
what were the results? In principle do you think this would be worth trying?
