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 &#x3bc;m.

Composition for non-pneumatic tire spoke

A rim for a non-pneumatic tire comprises a cylindrical rim wall portion, and a fixing member disposed to be spaced apart from the rim wall portion in a radial direction. The rim wall portion is provided with a fixing protrusion protruding in the radial direction or a fixing groove depressed in the radial direction.
