Now, Hankook has completed initial testing on its fifth-generation airless tire, dubbed the iFlex. The tires do not require any air pressure, instead relying on a new type of eco-friendly material (Hancook demurs when asked for details). Geometric shapes built into the material provide the bounce and springiness normally provided by air pressure. But, unlike the previous iFlex, this version's designed to mount onto a traditional rim, making it compatible with current vehicles.
Hankook ran the iFlex through a battery of tests to compare it to more conventional rubber, measuring durability, hardness, stability, slalom and speed, at up to 80 mph. The company says the tires matched conventional tires in terms of performance.
Anyone who got a flat from the epidemic of potholes this Spring or who is plagued by nails and other road debris that cause slow leaks will welcome this development. Naturally, the real question is whether it's spelled, "tire" or "tyre."

I don't think these will handle dirt or mud very well. They look clean in the picture, but imagine driving on dirt roads with those cavities. I can also imagine kids having fun with the cavities, putting stuff in just to see what will happen when ejected at high speed.
