Abstract: Provided is a tire provided with a mark capable of reducing the air resistance during tire rotation while maintaining good visibility. A tire is provided with a mark on a tire side portion. The mark includes a first mark located on an outer side in a tire radial direction, and a second mark located inward of the first mark in the tire radial direction. Each of the first mark and the second mark includes a recess that is recessed from a side profile surface of the tire side portion. A depth of the recess of the first mark from the side profile surface is smaller than a depth of the recess of the second mark from the side profile surface.

Abstract: A pneumatic tire 1 is provided in a bead portion 4 with a bead core 5 formed of a bead wire 20. The bead core 5 has a wound single bead wire structure formed from turns of the single bead wire 20, and has at least three wire layers 10. Each side face of the bead core 5 has a shape such that it is possible to draw a common tangent 30 to at least two turns of the bead wire 20 appearing in the side face 51 which common tangent is substantially parallel with the tire radial direction. The turns of the bead wire 21 in the 1st wire layer 11 are alternated with the turns of the bead wire 22 in the 2nd wire layer 12 disposed on the outside of the 1st wire layer 11. The 1st wire layer 11 includes a turn 21 having the winding-start end 16 of the bead wire, which turn 21 is positioned between adjacent two turns 22 of the bead wire in the 2nd wire layer 12.

Abstract: A tire includes a pair of beads, a carcass, chafers, an insulation, and cushion layers. Each bead includes a core positioned inward of the bead in a radial direction. At an inside of the core in the radial direction, the insulation is laminated on the chafers so as to be located outward of the chafers in the radial direction. Each cushion layer is laminated on the insulation so as to be located outward of the insulation in the radial direction. The insulation and the cushion layer are formed from respective crosslinked rubbers different from each other. A compressive elastic modulus Eα* of the crosslinked rubber of the cushion layer is smaller than a compressive elastic modulus Eβ* of the crosslinked rubber of the insulation.

Abstract: A pneumatic tire manufacturing method is provided in which winding collapse is prevented, there is no possibility of adverse effects on the FV, a current-carrying layer can be formed easily, and down-stitching can be dispensed with or minimized in the manufacture of SOT-structure pneumatic tires having a base-pen structure in the tread. This pneumatic tire manufacturing method involves: a step in which a sidewall, an inner liner, and a ply are bonded on a first molding drum, beads are set, and the tread side part that will form the current-carrying layer is formed on the side wall, forming a first cover; a step in which a breaker and band are bonded on a second molding drum and the tread center part is formed on the band, shaping the tread ring; a step in which the first cover is inserted inside of the tread ring and inflated to bond to the tread ring with pressure; and a step in which the sidewall is bonded to the lateral surface of the first cover, and the tread side part and the tread center part are bonded together.

Abstract: A tire 2 includes: a pair of beads 10 including cores 28; chafers 22, disposed near the beads 10, which are brought into contact with a rim; an inner liner 18 disposed inward of a carcass 32 in an axial direction; and an insulation 20 disposed between the carcass 32 and the inner liner 18 in the axial direction. The chafers 22 include bottom surfaces 22a that are brought into contact with the rim in portions inward of the cores 28 in a radial direction. The insulation 20 includes insulation lower portions 20a disposed between the cores 28 and the bottom surfaces 22a of the chafers 22 in the radial direction. The inner liner 18 includes inner liner lower portions 18a disposed between the cores 28 and the bottom surfaces 22a of the chafers 22 in the radial direction.
