Abstract
A non-pneumatic tire () of the present invention includes an attachment body () attached to an axle, a ring-shaped body () which surrounds the attachment body () from the outside in a tire radial direction, and coupling members () which displaceably couple the attachment body () to the ring-shaped body (), wherein a plurality of coupling members () are arranged in a tire circumferential direction and include elastic coupling plates (and) whose opposite ends are respectively coupled to the attachment body () and the ring-shaped body (), and a bending rigidity EI1 of the elastic coupling plates (and) represented by E1×W1×t1/12 when the average thickness in the tire circumferential direction is t1 (mm), the average width in a tire width direction H is W1 (mm), and the Young's modulus is E1 (MPa) is smaller than the bending rigidity EI2 of the ring-shaped body () represented by E2×W2×t2/12 when the average thickness in the tire radial direction is t2 (mm), the average width in the tire width direction H is W2 (mm), and the Young's modulus is E2 (MPa).
