1. A tire comprising:
a pair of beads each having annular bead cores and a bead filler extending to an outer side in a tire-radial direction of the bead core;
a carcass ply extending from one of the bead cores to another of the bead cores, and folded back around each of the bead cores;
a first pad disposed at an outer side in a tire-width direction of a folding end of the carcass ply;
a second pad disposed at an outer side in the tire-width direction of the first pad; and
a rim strip rubber disposed at least at a part on an outer side in the tire-width direction of the second pad,
wherein:
a steel chafer is provided so as to cover at least part of the carcass ply, and the rim strip rubber is provided at an inner side in the tire-radial direction of the steel chafer;
an electronic component is provided to interpose the second pad and the rim strip rubber;
the electronic component is disposed at a position distanced at least 5 mm from the folding end of the carcass ply;
in the tire-radial direction, the entire electronic component is disposed inside a tire-radial direction outside end of the bead filler and outside the folding end of the carcass ply;
a tire-radial direction inside end of the first pad is located between the carcass ply and the steel chafer, closer to an inner side in the tire-radial direction than a tire-radial direction outer surface of the bead core;
a tire-radial direction outside end of the first pad is located closer to an outer side in the tire-radial direction than a tire-radial direction outside end of the rim strip rubber; and
a tire-radial direction inside end of the second pad is located closer to an inner side in the tire-radial direction than a tire-radial direction inside end of the first pad.
 
14. A tire comprising:
a pair of beads each having annular bead cores and a bead filler extending to an outer side in a tire-radial direction of the bead core;
a carcass ply extending from one of the bead cores to another of the bead cores, and folded back around each of the bead cores;
a first pad disposed at an outer side in a tire-width direction of a folding end of the carcass ply;
a second pad disposed at an outer side in the tire-width direction of the first pad;
a rim strip rubber disposed at least at a part on an outer side in the tire-width direction of the second pad, and
a steel chafer is provided so as to cover at least part of the carcass ply, and the rim strip rubber is provided at an inner side in the tire-radial direction of the steel chafer;
a side-wall rubber located at an outer side in the tire-width direction of at least part of the rim strip rubber and the second pad,
wherein an electronic component is provided to interpose the second pad and the rim strip rubber;
the electronic component is disposed at a position distanced at least 5 mm from the folding end of the carcass ply and inward of the folding end of the carcass ply in the tire-radial direction,
a tire-radial direction inside end of the first pad is located between the carcass ply and the steel chafer, closer to an inner side in the tire-radial direction than a tire-radial direction outer surface of the bead core;
a tire-radial direction outside end of the first pad is located closer to an outer side in the tire-radial direction than a tire-radial direction outside end of the rim strip rubber;
a tire-radial direction inside end of the second pad is located closer to an inner side in the tire-radial direction than a tire-radial direction inside end of the first pad, and
a tire-width direction inner surface of the electronic component is disposed, in order, proximate the second pad, first pad, and carcass ply toward an inner side in the tire-width direction.
