The all new airless tire from Michelin recently came out into the publics eye early this year, 2005. Although it appears to be a pretty good idea and concept, they probably will not be available to the general public soon. I have looked at the idea and think it is cool, although I don't know what to think of the center rim selection that you haven't got a choice with. I'm sure that the police will probably not like the idea because the spike strips will definitely be ineffective with a set of these on your ride. The ride and handling seem to be very effective.
