TIRE
A tire includes a circular tire frame member formed from a frame-resin material and a covered cord member. The covered cord member includes a reinforcing cord provided in the tire frame member and extending along a tire circumferential direction, a covering-resin layer formed from a covering-resin material, covering the reinforcing cord, and bonded to the tire frame member, and a bonding-resin layer. The bonding-resin layer is formed from a bonding-resin material having an elastic modulus higher than that of the covering-resin material, is interposed between the reinforcing cord and the covering-resin layer, bonds the reinforcing cord and the covering-resin layer together, and has a layer thickness thinner than a layer thickness of the covering-resin layer.
TIRE WITH VARIABLE SHEAR ELEMENT
A tire includes a central region configured to be mounted to a wheel and a crown region including a circumferential tread and a shear element disposed below the circumferential tread. The shear element includes an upper reinforcement layer, a lower reinforcement layer, and an elastic region disposed between the upper reinforcement layer and the lower reinforcement layer. A radial distance between the upper reinforcement layer and the lower reinforcement layer varies along an axial width of the tire. The tire also includes an intermediate region extending from the central region to the crown region.

PNEUMATIC TIRE
Provided is a pneumatic tire that includes a belt reinforcing layer formed of an organic fiber cord. A belt layer disposed on an outer circumferential side of a carcass layer in a tread portion is formed of monofilament wires having a wire diameter of 0.30 mm or more and 0.45 mm or less. The belt reinforcing layer is disposed on an outer circumferential side of the belt layer, is formed of an organic fiber cord that is made of a polyethylene terephthalate fiber and has an intermediate elongation under 2.0 cN/dtex load of from 2.0% to 4.0%.
PNEUMATIC TIRE
A pneumatic tire including a belt constituted by at least one belt layer on a tire radial-direction inner side of a tread portion. The belt layer includes a reinforcing element containing plural metal filaments aligned in a single row without being twisted together is embedded in an elastomer. The tread portion includes: two or more circumferential main grooves arranged within a width of a ground-contact surface; and land portions, and widthwise sipes are arranged in at least one of center land portion. The widthwise sipes each include: a linear portion linearly extending from the surface of the tread portion toward the tire radial-direction inner side; and a bent portion extending from the linear portion toward the tire radial-direction inner side, and the length of the linear portion increases from an extending length center portion of each widthwise sipe toward at least one of tread widthwise end portions.
Pneumatic tire
The pneumatic tire according to the disclosure includes a resin-coated belt comprising a wire coated with a coating resin. A base ring is formed at a tire radial inside of the resin-coated belt, while being in contact with a tire widthwise outer end of the resin-coated belt. A concavo-convex portion is formed on at least one of surfaces of the base ring.
Radial tire for aircraft
A radial tire for an aircraft, the radial tire having a rim diameter of 20 inches or less includes a pair of bead portions; a pair of sidewall portions extending outward from the bead portions in a substantially radial direction; a tread portion that couples together respective radial outer ends of the sidewall portions; a toroidal carcass layer reinforcing a portion between bead cores embedded in the bead portions; a belt layer and a tread that are sequentially laminated on an outer side of the carcass layer in the radial direction, wherein a value M obtained by dividing a tire external diameter D by a distance L between bead heels of the bead portions is in a range of from 4.1 to 5.4.
PNEUMATIC TIRE
A pneumatic tire according to an embodiment is a pneumatic tire including a belt pad disposed between a belt end and a carcass ply. The belt pad is formed by a rubber composition containing 1 to 10 parts by mass of sulfur, 0.1 to 5 parts by mass of N,N-dibenzylbenzothiazole-2-sulfenamide, and 0.1 to 5 parts by mass of either one or both of 1,6-bis(N,N-dibenzylthiocarbamoyldithio)hexane and hexamethylene bis-thiosulfate disodium salt dihydrate, with respect to 100 parts by mass of diene rubber.
TIRE
In a tire 2, a tread 4 includes a cap layer 38 forming a part of the outer surface of the tire 2, an intermediate layer 40 disposed inwardly of the cap layer 38 in the radial direction, and a base layer 42 disposed inwardly of the intermediate layer 40 in the radial direction. A loss tangent of the intermediate layer 40 at 30° C. is less than a loss tangent of the cap layer 38 at 30° C., and a loss tangent of the base layer 42 at 30° C. is less than the loss tangent of the intermediate layer 40 at 30° C. An outer end PC of the cap layer 38 is disposed outwardly of an outer end PB of the base layer 42 in the axial direction. In the radial direction, a position of the outer end PC of the cap layer 38 coincides with a position of the outer end PB of the base layer 42, or the outer end PC of the cap layer 38 is disposed inwardly of the outer end PB of the base layer 42.
Pneumatic tire
A pneumatic tire is provided where a profile line in a tire meridian cross section of a center land portion defined by circumferential grooves and located on a tire equator is curved projecting outward in a tire radial direction. A carcass layer and a reinforcing layer include a recess portion curved projecting inward in the tire radial direction in a bottom region of the center land portion.
