It's of Michelin's new airless tires; yep, that's right, these tires have no air in them at all! Now tire technology has advanced to the point that we've seen tires that run deflated for up to an hour, but this one's got to be way out there.
They may not look that nice, but they're sure to be the next-generation of tires when they come out. It'll also force the police to rethink their tactics. I don't think a Stinger/spike strip will work very well against airless tires!
