A tire that lasts a lifetime would shed less particles than ~~one that needs replacing every so many miles~~ all the tires used in the same timeframe, would it not?
The reason tires need replacing is because they're relatively thin. Airless tires aren't wear-less tires.
Not to mention that airless tires make for a horrible ride.
Actually earlier prototypes were wear-less, from both companies that were developing them.
As for the horrible ride, from what I've seen, that's not a problem. But even if it was perhaps that should be solved by other aspects of the car.
They're not prototypes, they exist and they're called tweels. They're only really useful for low-speed industrial equipment where ride quality is a low priority.
