The reinforcing structure for a tire is in the form of a stratified assembly formed of two layers of reinforcing strips of completely connected cross section, and flattened in shape. According to the method, the strips of each layer are laid side by side in a main direction of laying. The strips of the first layer are spaced apart by a distance that is less than the width of the strips of the second layer and in such a way that the edges of the strips of the first layer overlap the edges of the strips of the second layer. The two layers of strips are separated by a layer of uncoupling rubber.

In a pneumatic tire that includes strip members which extends in a tire circumferential direction, both ends thereof reaching each bead portion, a belt layer is disposed in a tread portion on an outer side in a tire radial direction of the strip members. The strip members are divided in the tire width direction, and the divided strip members have joints that join together in the tire circumferential direction. Relative positions of the joints are disposed deviated by not less than 20 in the tire circumferential direction within a region between an edge of a maximum width in the tire width direction of the belt layer and a maximum tire width position.

A tire, including a circular tire frame formed of a resin material, the resin material including a resin composition in which at least one thermoplastic resin selected from the group consisting of a polyamide-based thermoplastic resin, a polyester-based thermoplastic resin, and a polyolefin-based thermoplastic resin, and at least one elastomer selected from the group consisting of a diene-based rubber, a vinyl acetate copolymer, a polyurethane, an ethylene propylene rubber, and any modified product thereof have been dynamically crosslinked.

In a pneumatic tire of this disclosure, in the reference condition, thickness of a sidewall portion in a tire radial region between positions each spaced apart, from a tire maximum width position, by 15% of tire cross-sectional height to inner side and outer side in the tire radial direction is 1.0 to 4 mm thicker than thickness of the thinnest part of the sidewall portion.

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 2 includes a buttress reinforcing layer 22. A carcass 12 includes a first ply 38 and a second ply 40. The first ply 38 and the second ply 40 each have a main portion that is extended on and between beads 10 on both sides. The buttress reinforcing layer 22 extends along the first ply 38 and the second ply 40 between the first ply 38 and the second ply 40. An outer end 22a of the buttress reinforcing layer 22 is disposed inward of a shoulder region S of a tread 4 in a radial direction. An inner end 22b of the buttress reinforcing layer 22 is disposed at a maximum width position of the tire or disposed outward of the maximum width position of the tire in the radial direction.

A pneumatic tire has carcass layers mounted between a pair of bead parts, the carcass layers being wound from the inner side of the tire to the outer side thereof about a bead core of each bead part. Protective layers including organic fiber cords are positioned in sidewall parts on the outer side of the carcass layers. The upper end parts of the protective layers are positioned along the carcass layers from outer end locations of the belt layers, between a location 20 mm toward the inner side in the tire width direction and a location 15 mm toward the outer side in the tire width direction. The lower end parts of the protective layers are positioned between main body portions of the carcass layers and the bead filler.

The invention relates to a bicycle tyre with high riding comfort. A damping rubber insert (3) made from a highly elastic rubber is arranged between the tyre tread (2) and the tyre carcass. Said damping rubber insert (3) has a material thickness of between 0.2 and 2 mm, and the carcass insert ends (10) extend to a maximum of the lateral edge areas of the tyre tread (2).
