I've seen these before, and it's great innovation. The performance you can get from a tire like that must be staggering, because it will maintain the correct tire patch without allowing the tire to 'roll over' in a hard turn like pneumatic tires. It's very possible this is the future for tires, but I would imagine for those who don't like the open spoke look, they can add a venier of rubber to appear like a regular tire.
Imagine how much lighter such a combination is compared to our 50lb EACH wheel/tire combinations?!
