Provided is a bead member comprising an annular bead core, and a bead filler located on an outer side of the bead core in a radial direction of the bead core, and the bead filler comprises a resin filler portion made of a resin and a rubber filler portion made of a rubber and joined to the resin filler portion.

In a tire 32, in a radial direction, a first end 92 of each filler 52 is located inward of a bead base line, and a second end 94 of each filler 52 is located between an end 88 of a turned-up portion 86 and the bead base line. Each bead 40 includes a core 64, a first apex 70 that surrounds the core 64, and a second apex 72 that is located outward of the first apex 70 in the radial direction. An outer periphery of the first apex 70 has a rounded contour. The first apex 70 is harder than the second apex 72.

A tire 32 includes: a pair of beads 40; a carcass ply 82 having a ply main body 84 and turned-up portions 86; and a pair of fillers 52 that are located outward of the turned-up portions 86 in the axial direction and that include metal cords. In a radial direction, a first end 92 of each filler 52 is located inward of a bead base line, and a second end 94 of each filler 52 is located between an end 88 of the turned-up portion 86 and the bead base line. A recess 96 is provided on a zone of each side surface 34 of the tire 32 between a maximum width position and the end 88 of the turned-up portion 86.

A tire includes a tread, a sidewall extending from one edge of the tread approximately in a radially inward direction to a bead structure, and a carcass extending along an axially inner side of the sidewall to the bead structure. The carcass includes a first ply and a second ply extending radially inward from the sidewall to a terminal end directly adjacent the bead structure. The bead structure includes a circumferentially extending bead core axially inward of the sidewall, a chafer extending radially inward toward the bead core, an apex abutting the bead core, and an inner stiffener member disposed between the first ply and the apex, the inner stiffener member extending radially outward from a location proximate the bead core to a location radially outward from the apex.

A tire includes: a bead core; a bead filler extending to an outer side in the tire-radial direction of the bead core; a carcass ply which is folded back around the bead core; a pad member disposed on an outer side in the tire-width direction of the bead filler; and a first rubber sheet disposed in a state covering a folding end of the carcass ply which is folded back, between the bead filler and the pad member, in which a second rubber sheet covering an electronic component is disposed between the bead filler and the pad member on an outer side in the tire-radial direction of the first rubber sheet.

A tire includes a pair of beads which have a bead core and a bead filler extending to an outer side in the tire-radial direction of the bead core; and a carcass ply extending from one bead to another bead and folded back around the bead core, in which the bead filler is formed by a number of filler pieces, and an electronic component is interposed one filler piece and another filler piece which are adjacent, whereby the electronic component is embedded inside of the bead filler.

A tire includes a pair of beads having a bead filler which extends to an outer side in the tire-radial direction of a bead core, and a carcass ply which extends from one bead to another bead and is folded back around the bead core, in which an electronic component is embedded in an area range of 10 mm to an inner side in the tire-radial direction from a tire-radial direction outside end of the bead filler.

A tire includes: a bead filler extending to an outer side in the tire-radial direction of a bead core; a carcass ply folded around the bead core; a steel chafer arranged so as to cover the carcass ply around the bead core; a first pad covering an outer side in the tire-width direction of a folding end of the carcass ply, at the outer side in the tire-radial direction of the end part of the steel chafer; a second pad covering an outer side in the tire-width direction of the first pad; and side wall rubber covering at least part of the outer side in the tire-width direction of the second pad, in which an electronic component is provided between the second pad and the side wall rubber.

A heavy-duty pneumatic tire includes a carcass ply including a main portion extending between bead cores and a pair of turn-up portions, a first reinforcing layer of a steel cord disposed in each bead portion in a U-shaped manner, and a second reinforcing layer of an organic fiber cord disposed in each bead portion and at least a part of the second reinforcing layer extending in a radial direction of the tire at an axially outward location of the first reinforcing layer. The second reinforcing layer includes an axially inner second ply and an outer second ply. The outer second ply has an inner end positioned below the bead core. The inner second ply has an inner end located axially inward of the inner end of the outer second ply, and has a substantially same length as the outer second ply in a tire cross-section.

A tire includes a bead portion with a bead core having a main bead filler and an auxiliary bead filler, and a carcass ply wrapped around a portion of the main bead filler. An end of the carcass ply is located axially outside the main bead filler and radially below an apex of the main bead filler. The auxiliary bead filler is located axially outside the carcass ply end, with an apex of the auxiliary bead filler being located above an apex of the main bead filler.
