Have seen concept a while back in Popular Science. Air or pneumatic tires are used because they deliver a smoother ride. Really old cars had skinney solid rubber tires that never went flat, but the ride I heard was terrible, and was good only for slow speeds. Neverthless, it was a tough sell at time to get people to use air when there was such a risk of a flat, but I'm sure the desire to drive faster helped move things along. Looks like we are now going between the two extremes. I see it is being used on construction equipment.
