Abstract: In a non-pneumatic tire, the plurality of connecting portions comprise first connecting portions extending in such fashion as to be directed from a first side in a tire width direction of an inner annular portion toward a second side in the tire width direction of an outer annular portion, and second connecting portions extending in such fashion as to be directed from the second side in the tire width direction of the inner annular portion toward the first side in the tire width direction of the outer annular portion, and at least one of the plurality of connecting portions comprises a main body portion having a width that is constant or that increases in tapered fashion by a constant ratio as viewed in the tire width direction, and an reinforcing portion that connects an end in a tire circumferential direction of the main body portion and the annular portion.

Abstract: A tire includes: a pair of beads having a bead core and a bead filler which extends to an outer side in a tire-radial direction of the bead core; a flipper which envelops at least part of the bead; a carcass ply which has a ply body extending from one bead to another bead, and a ply folding part which is folded back at the bead, and which envelopes the flipper; and an RFID tag as an electronic component embedded within the tire so as to make contact with the flipper.

Abstract: A tire includes: a pair of beads having a bead core and a bead filler which extends to an outer side in the tire-radial direction of the bead core; a carcass ply including a ply body which extends from one bead core to another bead core, and a ply folding part which is folded back around the bead core; a steel side ply serving as a metal reinforcement layer provided between the ply folding part and the bead filler; and an RFID tag serving as an electronic component provided between the bead filler and the ply body.

Abstract: A tire manufacturing method includes: a step of arranging rubber inside a spring antenna of an electronic component having a communication function, a step of interposing by rubber sheets the electronic component having the spring antenna into which rubber was arranged, and a setting step of arranging the electronic component interposed by rubber sheets in a tire.

Abstract: A traceable RFID tag which is capable of communication from at least the inner cavity side of the tire is arranged in a peripheral region of a bead core. This traceable RFID tag may be arranged at a position from which communication is not possible from outside of the tire when the tire has been mounted to the rim. In addition, a normal-use RFID tag which is capable of communication from outside of the tire when the tire had been mounted to the rim may be further equipped.

Abstract: A tire includes a number of ring-shaped tire structures which constitute the tire, and a ring-shaped rubber sheet which is integrated with an electronic component, in which the ring-shaped rubber sheet that is integrated with the electronic component is arranged between the number of ring-shaped tire structures.

Abstract: A tire includes a pair of beads which have a bead core and a bead filler extending to an outer side in the tire-radial direction of the bead core; and a carcass ply extending from one bead to another bead and folded back around the bead core, in which the bead filler is formed by a number of filler pieces, and an electronic component is interposed one filler piece and another filler piece which are adjacent, whereby the electronic component is embedded inside of the bead filler.

Abstract: A tire includes a carcass ply, a metal reinforcement layer which reinforces the carcass ply, an electronic component arranged in a vicinity of the metal reinforcement layer, and an insulating layer arranged between the metal reinforcement layer and the electronic component.

Abstract: A pneumatic tire includes: a tread portion; three or more main grooves provided on the tread portion at intervals in a tire width direction so as to extend in a tire circumferential direction; and a plurality of land portions partitioned between the main grooves adjacent to each other in the tire width direction, wherein the plurality of land portions include: ground contact areas having an arc shape in cross section in the tire width direction; and depressed portions opening to the ground contact areas, and the land portion having a larger ratio of opening surface area a of the depressed portions opening in the area between the main grooves adjacent to each other in the tire width direction with respect to surface area A of the area (a/A) has an arc-shaped ground contact area with a cross section in the tire width direction having a smaller radius of curvature.
