I bet we won't see them at all. Development of airless tires has been around
nearly as long as the car itself, a century later and we're still driving on air!
I think if Michelin wants to succeed with their airless tire, they have to make
it look like a conventional tire. In it's current form, I have little doubt
that consumers would reject it. The car looks like it has bicycle wheels on it!
