I have this small tube-type tire on a wagon. It went flat. I took

I gave up & tried something that I saw on YouTube - foam. I drilled
some holes in a sidewall and squirted in some Great Stuff. I left it
to harden and came back to this:

Not a problem, but definitely amusing.

So are you going to use it or exhibit it at the Tate Modern. I've not
used Great Stuff but have heard mention of it, is it a resilient foam
with some give in it or is it a hard foam.
