摘要： A pneumatic tire includes a tire case, a tread and a single-layer belt. The tire case includes a carcass that extends from one bead portion to another bead portion. An outer side portion of the carcass is covered with a side rubber layer formed of a first rubber material. The tread is disposed at the tire radial direction outer side of the tire case and is formed of a second rubber material. The belt is disposed between the tire case and the tread. The belt includes a resin-covered cord that is wound in a spiral shape. The resin-covered includes a cord covered with a resin with a greater tensile modulus of elasticity than the first rubber material and the second rubber material. The resin at one winding and another winding of the resin-covered cord, which are adjacent in the tire width direction, are welded together.

摘要： A tire including a tire frame member, a reinforcing layer, and projections. The tire frame member is circular and is formed from a resin material, and includes a bead portion, a side portion, and a crown portion. The reinforcing layer is provided at a tire radial direction outer side of the crown portion, and comprises a reinforcing cord extending in a direction intersecting the tire width direction, the reinforcing cord being covered by rubber. The projections are respectively formed at both tire width direction sides of the crown portion such that the reinforcing layer is interposed between the projections. Each projection projects toward the tire radial direction outer side, and includes a projection wall face contacted by a side face of the reinforcing layer at the tire width direction inner side of the projection.
