What happened? The prototype has a diameter ~3.5x the width while the 'production tire is ~6.5x. and it looks like a 'cheater slick'. Among the claimed benefits are lower road noise and better anti-hydroplaning. With that [lack of] circumferential grooves?

Skinny tires don't hydroplane because there is no plane to hydro on. It goes by the square of the width, a tire twice as wide displaces twice the amount of water twice the distance, so the force pushing the tire off the pavement is 4 times.
