Abstract
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.
Claims5
A tire comprising:
- a bead core;
- a bead filler which extends to an outer side in a tire-radial direction of the bead core;
- a carcass ply which extends from the bead core to another bead core and is folded around the bead core;
- a reinforcement ply disposed so as to cover the carcass ply around the bead core;
- a first pad which covers an outer side in a tire-width direction of a folding end of the carcass ply which was folded back, at an outer side in the tire-radial direction of an end part of the reinforcement ply;
- a second pad which covers an outer side in the tire-width direction of the first pad;
- side wall rubber which covers at least part of an outer side in the tire-width direction of the second pad;
- and
- a rubber sheet which is disposed between the bead filler and the first pad and covers an inner side in a tire-width direction of the folding end of the carcass ply which was folded back,
- wherein an electronic component is provided between the second pad and the side wall rubber, and the electronic component is sandwiched between two rubber sheets made of the same rubbers;
- wherein the electronic component includes an RFID chip and an antenna extending straight from the RFID chip to both sides of the RFID chip, and a central axis of the antenna overlaps with the RFID chip;
- and
- wherein when defining, in a cross-sectional view in the tire-width direction, as a reference distance a distance along a tire-width direction outside surface of the second pad from a tire-radial direction outside end of the second pad until a proximal part of a folding end of the carcass ply which is folded back,
- the electronic component is arranged at the tire-width direction outside surface of the second pad within a range from a position 40% of the reference distance until a position 50% of the reference distance from the tire-radial direction outside end of the second pad towards the inner side in the tire-radial direction.
