摘要： The present invention relates to a composition for a non-pneumatic tire spoke. In particular, the non-pneumatic tire spoke prepared from the composition for a non-pneumatic tire spoke has excellent mechanical properties. A composition for a non-pneumatic tire spoke includes a thermoplastic polyester elastomer, a silane-based interfacial binder, and silica particles. The silica particles have an average particle diameter of 100 to 300 μm.

摘要： A method of manufacturing an airless tire including a spoke unit includes a first step of injection-molding a first spoke part, a second spoke part, a third spoke part and a fourth spoke part in a disc-like shape. The method further includes a second step of forming a first spoke by fusing the first spoke part and the second spoke part. The method further includes a third step of forming a second spoke by fusing the third spoke part and the fourth spoke part, and a fourth step of forming the spoke unit by fusing the first spoke and the second spoke.
