Abstract

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.

Claims

1. A tire comprising:

a pair of beads having a bead filler which extends to an outer side in a tire-radial direction of a bead core; and

a carcass ply which extends from one bead to an other bead, and is folded back around the bead core,

wherein an electronic component is embedded in an area range of up to a position 10 mm to an inner side in a tire-radial direction from a tire-radial direction outside end of the bead filler,

wherein the electronic component is provided between the bead filler and the carcass ply, and

wherein the electronic component is mounted so that a longitudinal direction thereof follows a direction of a tangential line relative to a circumferential direction of the tire.

2. The tire according to claim 1, wherein the electronic component is embedded at a position which is 2 mm to 8 mm from the tire-radial direction outside end of the bead filler.

3. The tire according to claim 1, wherein the electronic component is provided between the bead filler, and a ply folding part of the carcass ply which is folded back around the bead core and disposed to an outer side in a tire-width direction relative to the bead filler.

4. The tire according to claim 1, wherein the electronic component is provided between the bead filler and a ply body of the carcass ply which is disposed at an inner side in a tire-width direction relative to the bead filler.

5. A manufacturing method of a tire which includes:

a pair of beads having a bead filler which extends to an outer side in a tire-radial direction of a bead core;

a carcass ply which extends from one bead to an other bead, and is folded back around the bead core, and

an electronic component being embedded in an area range of up to a position 10 mm to an inner side in a tire-radial direction from a tire-radial direction outside end of the bead filler,

wherein the electronic component is provided between the bead filler and the carcass ply, and

wherein the method comprises a step of mounting the electronic component so that a longitudinal direction thereof follows a direction of a tangential line relative to a circumferential direction of the tire.
