I got this in an email about a new tire in development. They don't require any air or pressure adjustments, cannot go flat, and are apparently immune to spike strips. The other pics are of a test run of these on an Audi. They are supposed to be available for regular consumer use in the next few years...
Even worse, these are in development:
I think they could be bennificial if they closed up the sidewalls, otherwise they are ugly. No word on how they add up in treadwear, durability, traction, handeling, etc.
