That's amazing. Perhaps I'll have to explain to my grandchildren what a "flat tire" is...
I would imagine that in production form the spokes would be covered by a protective layer of rubber that gave the tires a similar appearance to a conventional tire, but that's just me.

The peculiar evil of silencing the expression of an opinion is, that it is robbing the human race; posterity as well as the existing generation; those who dissent from the opinion, still more than those who hold it. If the opinion is right, they are deprived of the opportunity of exchanging error for truth: if wrong, they lose, what is almost as great a benefit, the clearer perception and livelier impression of truth, produced by its collision with error. ~John Stuart Mill, On Liberty
