These tires are airless and 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 tires:)
Just think of the impact on existing technology:
(1) no more air valves
(2) no more air compressors at gas stations
(3) no more repair kits
These are actual pictures taken in the South Carolina plant of Michelin. It will be awhile before they are available to the automotive industry.
