Nope.

In order to think through this take the current solution, your proposed solution, and write out some pros and cons and relative weight.

Punctures aren’t the end of the world. And people can go years without punctures.

The increased weight alone of solid rubber over air would come into play all the time. Similar for the cost of that extra material. And that’s even before you get into less obvious things like heat or ride quality.

That being said, there have been attempts at airless tires. A Google search for airless tire will bring up information that someone spent more time explaining not just what we effort some random people spare for a fresh comment on Reddit.
