PROBLEM TO BE SOLVED: To provide a non-pneumatic tire having excellent durability performance.SOLUTION: A non-pneumatic tire includes: an annular tread part 2 that is brought into ground contact with a road surface; an annular inner peripheral part 3 that is positioned on the tire-radius-direction inside of the tread part 2; and a plurality of connection parts 4 that connect the tread part 2 and the inner peripheral part 3 together. The read part 2 includes a first part 5 that is brought into ground contact with the road surface, and a second part 6 that includes an inner peripheral surface 2b on the side of the inner peripheral part 3. Thermal conductivity of the second part 6 is higher than that of the first part 5. 【課題】優れた耐久性能を有する非空気式タイヤを提供する。【解決手段】路面に接地する環状のトレッド部２と、トレッド部２のタイヤ半径方向の内側に位置する環状の内周部３と、トレッド部２と内周部３とを継ぐ複数本の連結部４とを含む非空気式タイヤ１である。トレッド部２は、路面に接地する第１部分５と、内周部３側の内周面２ｂを含む第２部分６とを含んでいる。第２部分６の熱伝導率は、第１部分５の熱伝導率よりも大きい。【選択図】図１
