Abstract
A tire including a bead core, a bead filler extending to an outer side in a tire-radial direction of the bead core, and a carcass play extending from the bead core to another bead core and folded back around the bead core, further including a steel chafer arranged so as to cover the carcass ply around the bead core, a first pad which covers outside in the tire-width direction of a folding end of the carcass ply at the outside in the tire-radial direction of an end part of the steel chafer, and a second pad which covers the outer side in the tire-width direction of the first pad, in which an electronic component is provided between the first pad and second pad.
Claims4
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 sidewall rubber and a rim strip rubber which constitute portions of an outer surface in a tire-width direction of the tire;
- a rubber sheet covering an inner side in the tire-width direction of a folding end of the carcass ply which was folded back;
- a first pad which covers and contacts an outer side in the tire-width direction of the folding end of the carcass ply which was folded back and an outer side in the tire-radial direction of an end part of the reinforcement ply, contacts outer sides in the tire-width direction of the rubber sheet and the bead filler, and extends outward in the tire radial direction;
- and
- a second pad which covers an outer side in the tire-width direction of the first pad, and which is provided between the first pad and the rim strip rubber, and interiorly of the sidewall rubber in the tire-width direction, and contacts inner sides in the tire-width direction of the rim strip rubber and sidewall rubber;
- wherein an electronic component is provided between the first pad and the second pad,
- wherein the electronic component is provided at a position distanced by at least 5 mm from the folding end of the carcass ply, and
- wherein the second pad extends outward in the tire radial direction and sequentially contacts outer sides in the tire width direction of the reinforcing ply, the first pad, bead filler and the carcass ply in the extending direction of the second pad.
