The invention discloses a non-pneumatic tire with wave-shaped extended periodic structure and its processing method, belonging to the technical field of non-pneumatic tires. The non-pneumatic tire is manufactured from tire strips extruded by a screw extruder, and the tire strips include crown, belly and sidewall parts. The belly grooves of the tire strips are aligned with the core components of the middle mold, and the tire strips are wrapped around the outer side of the mold core. The mold core forms a wave-shaped extended periodic inner cavity supporting structure inside the tire, which consists of multiple groups of interconnected cavities distributed circumferentially along the belly grooves. This structural design ensures that the tire maintains the excellent comfort of traditional annular cavity structures and possesses sufficient supporting strength of conventional cavity structures.
