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.
