A tire for a motor vehicle comprising: two beads (20); two sidewalls (30) meeting at a crown (25); at least one carcass reinforcement (160) extending from the beads (20) through the sidewalls (30) as far as the crown (25), the carcass reinforcement (160) having a plurality of carcass reinforcing elements and anchored in the two beads (20) by a turn-up around the annular reinforcing structure (70), so as to form in each bead a main strand (162) and a turn-up strand (163); and a stiffening reinforcement (140) arranged in at least one sidewall of the tire, said stiffening reinforcement (140) having a radially inner end (141) and a radially outer end (142), the stiffening reinforcement being formed of a plurality of stiffening elements oriented at an angle less than or equal to 10 relative to a circumferential direction of the tire.

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.

An electronic component covered by rubber sheets is arranged on a tire outer surface side of a carcass ply in a region between a tire-radial direction outside end of a bead filler and a tire-width direction outside end of a steel belt. The rubber sheets include a first rubber sheet arranged on a tire inner cavity side of the electronic component, and a second rubber sheet arranged on a tire outer surface side of the electronic component; and the second rubber sheet is configured from a rubber sheet which is more difficult to deform than the first rubber sheet.

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 run-flat tire has: a pair of bead cores, each bead core formed by covering a wire with resin; a carcass that straddles the pair of bead cores, and having end portions that are anchored on the bead cores; side reinforcing rubbers that are provided at tire side portions, and that extend in a tire radial direction along an inner surface of the carcass; and a tread that is provided at an outer side, in a tire radial direction, of the carcass.

A tire includes tread having at least one ring-shaped steel belt extending in a circumferential direction of the tire, and a pair of beads having bead filler extending to an outer side of a tire-radial direction of the bead core, in which an electronic component is embedded in a region between a tire-radial direction outside end of the bead filler and a tire-width direction outside end of the steel belt.

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 carcass ply, a metal reinforcement layer which reinforces the carcass ply, an electronic component arranged in a vicinity of the metal reinforcement layer, and an insulating layer arranged between the metal reinforcement layer and the electronic component.
