The military also has a self’sealing tire that can be shot up and heal its own bullet holes. I saw a PBS special on this recently.
But realize that all these technologies come with tradeoffs. When you’re invading a foreign country with no roads, the ability to self-heal is far more important than ride, handling, mileage, and even cost. A flat is no big deal in a POV on a highway in the states. In a convoy in a war zone it can mean life or death, or success or failure of a mission.
The conventional tire actually works pretty doggoned well for the extreme variaty of conditions it has to operat under. And flats in modern tires are really pretty rare, as long as they’re not subjected to neglect or abuse. Or drive until the cords show.
