Abstract: A pneumatic tire includes: a tire inner surface rubber layer constituting a tire inner surface; and an electrically conductive member, at least a part of the electrically conductive member being disposed on an inner cavity side of the tire inner surface rubber layer. The electrically conductive member includes a knitted fabric including a yarn, at least a part of the yarn having electrical conductivity, the knitted fabric having stretchability. The electrically conductive member is electrically connected to an electrical device provided in the tire. The electrically conductive member is disposed extending along the tire inner surface in a tire radial direction, and a direction in which the electrically conductive member extends aligns with a direction in which the knitted fabric has stretchability. The knitted fabric is configured by mixing a yarn having electrical conductivity and a yarn having non-electrical conductivity.

Abstract: In this pneumatic tire, the bead core has a predetermined wire array structure obtained by arranging wire cross-sections of bead wires in a cross-sectional view in a tire meridian direction. The following are defined in the wire array structure: a tangent line that contacts, from the side of a rim fitting face, an innermost layer in the tire radial direction and the wire cross-section on the innermost side and the outermost side in the tire lateral direction; contact points of the tangent line with respect to the wire cross-sections on the innermost side and the outermost side; a middle point of the contact points; and gauges in the tire radial direction from the contact points and middle point to the rim fitting face. In this case, the change rates of the gauges before and after rim assembly each are in the range of 10% to 60%.

Abstract: Of layers configuring a bead core of a pneumatic tire, the width W0 of one of the layers including the greatest number of rows, the width W1, W2 of other of the layers located respectively innermost and outermost in the radial direction satisfy W1>W2 and W2≤0.5×W0. The position of width W0 is inward in the radial direction of the center of the bead core. A carcass is folded and curved along the bead core and extends toward sidewalls where a folded back portion of the carcass contacts a body of the carcass. A rubber occupancy ratio in a closed region formed by the body and the folded back portion is 0.1% to 15%. The cross-sectional area S2 and hardness H2 of a filler outward of the carcass in the lateral direction, and the cross-sectional area S1 and the hardness H1 of the side reinforcing layer satisfy 0.12≤(S2×H2)/(S1×H1)≤0.50.

Abstract: Provided is a pneumatic tire comprising a tread section, a side wall section, and a bead section. A tire constituent member is provided in at least the tread section, extending along the tire circumferential direction and spliced at any positions in the tire circumferential direction. A belt-shaped sound-absorbing member is adhered to a region corresponding to the tread section in the tire inner surface, along the tire circumferential direction and via an adhesive layer. The sound-absorbing member is arranged intermittently along the tire circumferential direction. Sections where the sound-absorbing member is missing are arranged at positions corresponding to the splice portions of the tire constituent member and the sound-absorbing member is arranged so as to not overlap the splice portions.

Abstract: A pneumatic tire includes a planar-shaped receiver coil in a cavity region, and configured to receive a magnetic field through a carcass ply layer and generate a signal, and an element to receive power converted from the signal. A receiving region of the receiver coil is interposed between an outermost side of a bead core in the radial direction and an innermost side of a belt layer in the radial direction, and the receiving region faces in the width direction. When a maximum dimension of the receiving region along the radial direction of the receiver coil is a length D1, a distance from the receiving region to a nearest portion of the bead core to the receiving region is L1, and a distance from the receiving region to a nearest portion of the belt layer to the receiving region is L2, relationships L1>(D1/4) and L2>(D2/4) are satisfied.
