The “Air Free Concept” is a technology that eliminates the need for tires to be inflated with air to support the weight, using a unique structure of spokes stretching along the inner sides of tires. In addition, “the resins that are used in the spokes and rubbers help realize more efficient use of resources,” said the company in an official release.
