I don't want to derail this thread, but that tire concept and its associated website and media seems very heavy on marketing and very light on facts... there's a lot of fancy graphics and interesting looking dyno time, but not much in the way of results to prove their theory. They are also looking for your donations to "Fight Big Oil".

50% coast down improvement video is completely fact-less, other than a timer. I also notice the outside diameter of the tires is far greater than their prototype wheels.

It would be nice if it were real. If everything is patented I'm not sure why they wouldn't share more on their tech, especially if they're looking for investors.

Anyway, back on topic...
