Abstract:
A tire includes a tire frame member that is formed from a resin material and has a bead portion, side portions, and a crown portion, a belt layer serving as an example of a reinforcing layer that is disposed at the outer side in a tire radial direction of the tire frame member, and has a higher bending rigidity than outer circumferential portions of the tire frame member, a top tread serving as an example of a tread that is formed from a rubber material and is disposed at the outer side in the tire radial direction of the belt layer, and first width direction grooves serving as an example of width direction grooves that are provided at the top tread. An aperture surface area of one of the first width direction grooves within a total ground contact surface of the tread of one circumferential direction portion of the tire is 0.02% or less relative to a surface area of a total ground contact surface of the tread of one circumferential portion of the tire.
