Goodyear has put out a pretty cool video for spherical wheels:
(Eagle 360 spherical wheel prototypes)
The wheels are dubbed “Eagle-360”. According to the concept video, the wheels are held in place by magnetic levitation. Sponge-like grooves in the tries dampen when wet to resist hydroplaning. The spherical wheels shake off excess water like a dog. When dry, the sponge hardens and the wheels are again made for speed. Sensors in the tires read road conditions and communicate them to other cars. The spherical wheels will scan themselves for wear and tear and adjust alignments as needed, so that it’s not wearing down the same strip of wheel all the time.
As we all remember (and maybe the Goodrich Eagle-360 team?) from the 2004 movie I, Robot, cars with spherical wheels are highly maneuverable, as are truck transports.
