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, the carcass ply having a folding end that is folded back around the bead core;
- a chafer arranged 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 which covers the folding end of the carcass ply which has been folded back, the rubber sheet having a uniform thickness in the tire-radial direction;
- a first pad which covers and contacts an outer side, in the tire-width direction, of the folding end of the carcass ply, and an outer side, in the tire-width direction, of the rubber sheet, 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 outer side, in the tire radial direction, of the first pad, tapers while approaching an outer side in the tire-radial direction;
- and
- wherein an electronic component is provided between the bead filler and the rubber sheet and in direct contact with the bead filler and the rubber sheet.
