    Abstract: Provided is a low noise pneumatic tire in which the noise absorbing member on the inner peripheral surface of the tire is made less likely to be damaged when the pneumatic tire is removed from the rim. The pneumatic tire includes a noise absorbing member of a porous material which is attached to an inner peripheral surface of the tire. In the pneumatic tire, a lubricant is applied to the inner peripheral surface of the noise absorbing member. Alternatively, both end portions, in a tire width direction, of the inner peripheral surface of the noise absorbing member are covered with protective layers harder than the noise absorbing member.

    Abstract: The pneumatic tire of the present technology includes: a tread portion; sidewall portions; and bead portions. A pattern of grooves is formed on the tread portion, and a strip-shaped sound-absorbing member is bonded along the tire circumferential direction to a region of the tire inner surface corresponding to the tread portion via an adhesive layer. A first ground contact region is defined between the tire ground contact edge on one side in the tire width direction and the tire equatorial plane, and a second ground contact region is defined between the tire ground contact edge on the other side in the tire width direction and the tire equatorial plane. The sound-absorbing member is offset with respect to the tire width direction so that the centroid of a cross-section of the sound-absorbing member in a plane that includes a tire axis is located within the first ground contact region.

    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: In a pneumatic tire including a side reinforcing layer, the maximum width W0 of a bead core and the widths W1, W2 of the bead core at innermost and outermost sides in the radial direction, respectively, satisfy W1>W2 and W2≤0.5×W0. W0 is toward the inside of the center of the bead core in the radial direction. A carcass is folded and curved along the bead core, and a folded back portion of the carcass extends toward the sidewalls while contacting a body of the carcass. A rubber occupancy ratio in a region formed by the body and the folded back portion of the carcass is 0.1% to 15%. The cross-sectional area S2 of a filler toward the outside of the carcass in the lateral direction, the hardness H2 of the filler, the cross-sectional area S1 of a side reinforcing layer and the hardness H1 of the side reinforcing layer satisfy 0.15≤(S2×H2)/(S1×H1)≤0.60.

    Abstract: A tire assembly includes a tire and a shape measurement unit utilizing magnetism. The shape measurement unit is provided with one device of a magnetic generator or a magnetic sensor configured to detect a distance of separation from the magnetic generator based on a magnetic field generated by the magnetic generator to acquire a deformation state of a sidewall, in a first region that is any one of a tread-portion-corresponding region and bead-portion-corresponding regions that are on an inner surface of the tire, the tread-portion-corresponding region corresponding to a tread portion and the bead-portion-corresponding regions corresponding to bead portions, and is provided with another of the magnetic generator or the magnetic sensor in a second region.

    Abstract: In a pneumatic tire, a turned back portion of a carcass layer contacts a body portion of the carcass layer in a cross-sectional view in a tire meridian direction to form a closed region surrounding bead cores. A rubber occupancy ratio in the closed region is in a range of 15% or less. The bead cores have a predetermined wire arrangement structure formed by arranging wire cross sections of bead wires in the cross-sectional view in the tire meridian direction. Additionally, a self-contact height (CH) of the carcass layer and a circumferential length (L) of the wire arrangement have a relationship 1.0≤CH/L≤10.0.
