Abstract

Provided is a solid tire capable of maintaining tire stiffness while molding defect of a protrusion disposed in a base rubber layer is prevented. Provided is a solid tire 1. The solid tire 1 includes: a base rubber layer 11 configured to be mounted on a sideringless rim 2; and a tread rubber layer 12 disposed outward of the base rubber layer 11 in a tire radial direction. A protrusion 14 is disposed on an inner circumferential surface 13, in the tire radial direction, of the base rubber layer 11 so as to protrude inwardly in the tire radial direction on one side in a tire axial direction. The base rubber layer 11 includes a base inner circumferential layer 11A forming the inner circumferential surface side portion including the protrusion 14, and a base outer circumferential layer 11B disposed outward of the base inner circumferential layer 11A in the tire radial direction. The base inner circumferential layer 11A is formed of a first rubber material 31 in which no fibers are blended. The base outer circumferential layer 11B is formed of a second rubber material 32 in which one or more fibers are blended.
