The army has been testing these for several years now.
Resilient Tech was developing them for the military.

Radical new tire design by Michelin.

The next generation of tires.

They had a pair at the Philadelphia car show.

Those are ‘spoke’ like connections to the inner partof the tire from the outside tread ‘wrap!’ The next picture shows how odd it looks in motion.

Makes you wonder how the ride feels, doesn’t it?

These airless tires are scheduled to be out on the market very soon.
The bad news for law enforcement is that spike strips will not work on these.
Just think of the impact on existing technology:

A. No more air valves.
B. No more air compressors at gas stations.
C. No more repair kits.
D. No more flats.

These are actual pictures taken at the Michelin South Carolina plant.
