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.
  
This is what great R&D will do, and 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
 
 SCAN  DOWN & SEE.
 
These are actual pictures taken
in the South Carolina plant of Michelin.
It will be awhile before they are available
to the automotive industry.
