...and then you've got something.

I'm actually surprised that I've never seen a tire with some kind of closed-cell super lightweight foam, some kind of aerogel maybe. I suppose the problem in that case is that you can't spread heat throughout the whole interior.

Which makes me wonder, how do they radiate heat on this Michelin? Does it stick around the outer surface and that's it? Do the 'spokes' bear it away somehow?

In the off-road motorcycle industry there are these tubes called mousse bibs. I run them on all my bikes. They do replace the inner tubes, not the tires themselves. But they work great and are the best anti-flat solution out there. They sound similar to what you’re talking about. Michelin makes them too.

I have something similar for my mountain bike, CushCore. They don't replace inner tubes (tubeless setup) but they do add a lot of protection, dampening and deflection.

The name “Bib mousse” was created by Michelin - Bib is short for Bibendum, which is the name of the Michelin man, and mousse is French for foam.
