Spherical Tires Provide Magnetic Levitation

The Eagle 360, a new tire design concept from Goodyear, is a rounded sphere held in place by magnetic fields and designed for a smoother ride in your future driver-free car. An organically-patterned, 3D-printed tread is designed to adapt like a sponge to different road conditions, while built-in sensor relay surface measurements to the onboard computer. Faster response times and immediate reaction capabilities in multiple directions all work toward improving passenger safety and comfort.
