Global Air Cylinder Wheels (GACW), an Arizona-based startup, has literally reinvented the wheel. They developed a new type of wheel that ditches the need for pollutive rubber tires.
Many companies have tried to create new tire solutions, such as Tesla possibly moving toward airless tires on its Model 3, but none have succeeded so far.
