A non-pneumatic tire (NPT), unlike a pneumatic tire, is a tire that acts as air pressure with spokes, and has the advantage of not requiring maintenance of air pressure and the risk of puncture of the pneumatic tire. Recently, many technological advances are taking place in non-pneumatic tire (NPT) using artificial intelligence technology, and non-pneumatic tire manufacturers are actively conducting research and development. Here, in order to compare and analyze the technological competitiveness of major patent applicants, non-pneumatic tire-related patents that have been applied for Japan, the United States, China, Korea, Germany, France, and the European Union Patent Office are reviewed through the patent applications of global tire manufacturers.
