A tire is provided with a tire frame member that is made from resin and has a pair of bead portions, a pair of side portions that extend from the bead portions towards an outer side in a tire radial direction, and a crown portion that connects an outer side end in the tire radial direction of one side portion to an outer side end in the tire radial direction of another side portion, and with a crossing belt layer that is provided with plural reinforcing cords that are arranged in rows which are inclined relative to a tire rotation axis of the tire frame member and are coated with a resin material. The crossing belt layer is disposed either directly or via a resin layer on an outer side surface in the tire radial direction of the crown portion.

A tire, including: a tire frame member formed of a resin material; and a reinforcing layer that includes a plurality of reinforcing cords coated with a rubber material and that is disposed on an outer side of the tire frame member in a tire radial direction; in which the tire frame member has a region formed of a resin material having a Young's modulus in a range of from 50 MPa to 2,000 MPa, and the region being included in at least a part of a reinforcing region in which the reinforcing layer is disposed on an outer side in the tire radial direction.

The problem of this disclosure is to provide a non-pneumatic tire that achieves both ride comfort and durability, even in a small diameter size. The solution is a non-pneumatic tire (1) using a resin composition as a skeletal member, wherein the resin composition has a bending modulus of elasticity of 247 MPa or less at ?20? ? C. in accordance with ISO 178 and a bending modulus of elasticity of 32 MPa or more at 60? C. in accordance with ISO 178, and a tire diameter D in the tire radial direction is 35 cm or less.
