What about airless tires? I havent looked deeply into them but they sound like they would not be as profitable since you will be less likely to change tires due to a nail certainly reducing sales. But I am not sure what kind of cars these tires compliment and what kind of driving they are not for.
Understandable, I hadn't looked into them as much or the subject matter. I'm curious if airless tires with similar design but different material could be made.
Their claim of low rolling resistance is surprising to me, since all the non-pneumatic designs similar to that I've seen before had abysmal rolling resistance. It seems their prototype is still in development, so maybe that claim represents their ambitions, not their achievement thusfar. Although, looking at the render of the product they've provided, it looks pretty dang narrow compared to the "ecopia" brand tires they're compared against. It could be they've reduced rolling resistance by simply making it narrower than an otherwise equivalent pneumatic tire.
