To provide a thermo-curable resin composition that can improve durability of a non-neumatic tire.SOLUTION: A thermo-curable resin composition is used for manufacture of a support structure 10 of a non-pneumatic tire 1. The thermo-curable resin composition contains polyol and polyisocyanate, and has an isocyanate index of 1.00 or more and 1.20 or less. The non-pneumatic tire 1 comprises: the support structure 10; and a tread 50 which is positioned in a tire radial direction outer side with respect to the support structure 10 and extends along a tire circumferential direction. The support structure 10 contains the afore-said thermo-curable resin composition. A manufacturing method for the non-pneumatic tire 1 includes a process in which the thermo-curable resin composition is thermally cured to manufacture the support structure 10.SELECTED DRAWING: Figure 1

    【課題】非空気圧タイヤの耐久性を向上させることが可能な熱硬化性樹脂組成物を提供する。【解決手段】熱硬化性樹脂組成物は、非空気圧タイヤ1の支持構造体10の製造に使用される。熱硬化性樹脂組成物は、ポリオールおよびポリイソシアネートを含み、イソシアネートインデックスが1.00以上1.20以下である。非空気圧タイヤ1は、支持構造体10と、支持構造体10よりもタイヤ径方向外側に位置しており、タイヤ周方向に沿って延びているトレッド50と、を備える。支持構造体10は、上記の熱硬化性樹脂組成物の硬化物を含む。非空気圧タイヤ1の製造方法は、上記の熱硬化性樹脂組成物を熱硬化させて支持構造体10を製造する工程を含む。【選択図】図1
