A tire comprising:
- a pair of beads each having a bead core and a bead filler extending to an outer side in a tire-radial direction of the bead core;
- a carcass ply extending from one bead to another bead;
- an inner liner disposed at a tire inner cavity side of the carcass ply;
- and
- an electronic component unit adhered to a tire inner cavity side of the inner liner, and
- wherein the electronic component unit comprises an electronic component and at least one resin film covering at least part of the electronic component, and the entire electronic component is disposed at a tire-radial direction position distanced at least 5.0 mm to an outer side in the tire-radial direction from a tire-radial direction outside end of the bead core;
- wherein the electronic component unit has a curved shape formed in a state adhering with the tire inner cavity side of the inner liner, and the curved shape comprises two protrusions protruding into the inner liner,
- wherein the tire further comprises a vulcanizing adhesive which bonds the inner liner to the curved shape of the electronic component unit, ensuring a seamless alignment of profiles of the inner liner, the vulcanizing adhesive, and the electronic component unit;
- and
- wherein an entire inner surface of the electronic component unit is adhered to the tire inner cavity side of the inner liner;
- wherein the at least one resin film is configured by a first resin film and a second resin film,
- wherein the vulcanizing adhesive, the second resin film, the electronic component and the first resin film are disposed in order on the tire inner cavity side of the inner liner, and
- wherein a thickness of each protrusion protruding into the inner liner is larger than a total thickness of the first resin film and the second resin film.
