A pneumatic tire includes a tread portion, sidewall portions, bead cores, an inner member including side portions and being continuous between the bead cores, a discontinuous ply disposed on an outer side in a tire radial direction of the inner member, and including ply pieces each having an inner end portion disposed in the tread portion, a side portion, and a winding portion wound up on the bead cores, a belt covering inner ends portion of the ply from the outer side in the tire radial direction, first joining members arranged between the inner end portions of the ply pieces and the inner member, and a pair of second joining members arranged between the inner end portions of the ply pieces and the belt, and each including an extending portion extending toward an outer side in a tire width direction beyond an end portion of the belt.

A pneumatic tire including a tread portion, a pair of sidewall portions, a pair of bead cores, a first ply, and a second ply being discontinuous and having a pair of ply pieces. The first ply includes a central portion positioned in the tread portion, a pair of side portions extending from opposite ends of the central portion, and a pair of folded-up portions folded up around the respective pair of bead cores. The pair of ply pieces each includes a side portion extending from an inner end, and a folded-up portion folded up around any one of the pair of bead cores. In each of the sidewall portions, the first ply has a plurality of first cords extending in the tire radial direction, and the pair of ply pieces each has a plurality of second cords extending at an angle from the first cords.

A pneumatic tire includes bead cores, a carcass ply and a belt. The carcass ply includes: a first ply having a central portion positioned inward of the belt in the tire radial direction, a pair of side portions extending inward from opposite ends of the central portion in the tire radial direction, and folded-up portions extending from the respective side portions, being folded up around the respective bead cores; and a second ply being discontinuous and disposed outward of the first ply in the tire radial direction, having a pair of ply pieces provided with inner ends positioned on respective sides of the central portion of the first ply, side portions extending inward from the respective inner ends in the tire radial direction, and folded-up portions extending from the respective side portions, being folded up around the respective bead cores. The first ply has a ply-overlapping portion.

Provided is a tire (10) including: a tire frame member (12) made of a resin; a reinforcing layer (16) that includes plural reinforcing cords (17) coated with a rubber material, and that is arranged on a tire radial-direction outer side of the tire frame member (12); and an adhesive layer (18) that contains a resin material, and that is arranged between the tire frame member (12) and the reinforcing layer (16).

A tire whose pressure-proofing performance and impact durability can be improved, is provided. The tire includes: a tire frame member which is made of resin and includes: a bead portion covering a bead core; a side portion extending outwardly in a tire radial direction from the bead portion; and a crown portion extending inwardly in a tire width direction from the side portion, and the tire also includes a reinforcing layer which includes plural cords covered by resin or rubber and which extends from the bead portion to the side portion of the tire frame member to cover at least an inner peripheral surface of the side portion.

A pneumatic tire includes a tread portion, a pair of sidewall portions, a first ply, and a discontinuous second ply composed of a pair of ply pieces. The first ply has a central portion and a pair of first side portions extending from both ends of the central portion to the inner side in the tire radial direction. Each of the ply pieces has an inner end portion disposed on the outer side in the tire radial direction of the central portion and a second side portion extending from the inner end portion to the inner side in the tire radial direction. The first ply is provided with a plurality of ventilation holes, and the density of the ventilation holes in the central portion is higher than the density of the ventilation holes in the pair of first side portions.

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.

This pneumatic tire is provided with: a pair of carcass layers arranged so as to extend from the respective left and right beads of the tire across the tread; and a plurality of crossing belts arranged on the outside of the carcass layers in the radial direction of the tire. The pair of carcass layers is arranged so as to overlap each other in the tire width direction. The overlapping width (Wc) of the carcass layers is in the range of 0.5 mmWc40 mm.

A pneumatic tire includes a strip member which extends in a tire circumferential direction, with both ends thereof reaching each bead portion, and a belt layer disposed in a tread portion on an outer side in the tire radial direction of the strip members. The strip members are divided in the tire width direction, with each of the divided strip members having joints that join in the tire circumferential direction. The relative positions of the joints are disposed at less than 20 in the tire circumferential direction within the region of the maximum width TW in the tire width direction of the belt layer.

An intermediate article of manufacture formed as a first stage bead area subassembly for a split ply pneumatic tire carcass is disclosed. The bead area subassembly has an annular bead core; a bead apex; a ply strip; and preferably a sidewall affixed to the ply strip. The subassembly is formed into a disk-shaped bead area monocomponent. The ply strip is wrapped about the bead core and the apex to form a ply turnup and both the ply strip and the ply turnup extend radially outwardly from the bead core. The bead area subassembly when formed into the disk-shaped bead area monocomponent is placed on an annular holder device.
