A run-flat tire has a belt-end reinforcing layer provided between the tread portion and a width outside end of the belt layer, and formed of a resin material. The belt-end reinforcing layer is annular along a tire circumferential direction, has a predetermined width along the tire width direction, and is provided in the tire width direction so as to cover a radial outside end of a side reinforcing rubber and a width outside end of the belt layer.

A pneumatic tire is provided with a belt in which reinforcing cords are embedded in resin. A graph shows proportional belt chamfer height BWH values on a horizontal axis X and proportional tread chamfer height TWH values on a vertical axis Y. The proportional tread chamfer height TWH and proportional belt chamfer height BWH are specified so as to fall in a region of this graph that is bounded by a straight line expressed by the formula Y=−2.43X+17.9. This region is at the side of the straight line at which the proportional tread chamfer height TWH and proportional belt chamfer height BWH are smaller.

A tire includes: an annular tire frame member; and a belt layer that is provided at an outer periphery of the tire frame member, wherein the belt layer includes a reinforcing cord spirally wound at intervals in a tire width direction, a resin layer that surrounds the reinforcing cord and integrally covers the reinforcing cord across an entire area of the reinforcing cord in the tire width direction, and a bonding layer that is bonded to one surface of the resin layer.

A tyre includes a tread portion being provided with a pair of shoulder circumferential grooves on an outer surface thereof and a tread reinforcing layer disposed in the tread portion. The tread reinforcing layer includes a circumferential belt layer having a plurality of first reinforcing cords oriented along a tyre circumferential direction. The circumferential belt layer includes a pair of axially spaced first circumferential belt plies extending in radially inner regions of the pair of shoulder circumferential grooves. The pair of first circumferential belt plies is arranged apart from one another at a distance L equal to or more than 20 mm in a tyre axial direction.

A pneumatic tyre 1 includes a carcass 6 extending between bead cores of bead portions via a tread portion 2 and sidewall portions, and a belt layer 7 arranged on an outer side in a tyre radial direction of the carcass 6 and inside of the tread portion 2. The pneumatic tyre 1 has a damping rubber body 30 arranged between the carcass 6 and the belt layer 7, and a noise damper 20 arranged on an inner cavity surface of the tread portion 2. A width W1 in a tyre axial direction of the damping rubber body 30 is in a range of from 60% to 130% of a width W2 in the tyre axial direction of the belt layer 7, and air permeability of the noise damper 20 measured in accordance with the Japanese Industrial Standard JIS-L1096 is 3.0 cm3/cm2/s or less.

A pneumatic tire according to the present disclosure is a pneumatic tire comprising an annular rubber-coated belt including a cord and a coating rubber with which the cord is coated, and comprises a resin layer located inside or outside the rubber-coated belt in a tire radial direction, and having an elastic modulus larger than an elastic modulus of the coating rubber, and a cushion material interposed in at least a space between an outer end of one of the rubber-coated belt and the resin layer in a tire width direction and the other one of the rubber-coated belt and the resin layer, and having an elastic modulus smaller than the elastic modulus of the coating rubber.

Provided is a pneumatic tire comprising a carcass straddling between bead portions and extending toroidally, a belt including a cord, and a coating material made of a resin or a rubber and with which the cord is coated, the belt being disposed at a position outside a crown portion of the carcass in a tire radial direction, and a resin layer disposed between the carcass and the belt or at a position outside the belt in the tire radial direction, the resin layer being in contact with the coating material of the belt, and an outer end of the resin layer in a tire width direction is located, in the tire width direction, at the same position as in an outer end of the belt in the tire width direction, or located, in the tire width direction, outside the outer end of the belt in the tire width direction.

A tire includes tire frame members including bead cores, a bead filler, an inner liner, side-wall rubber and cushion rubber; and an electronic unit provided at an interface of tire frame members, the tire further including: a carcass ply which extends from one bead core to another bead core and includes a rubber-coated reinforcement cord, a belt disposed on the outer side in the tire-radial direction of the carcass ply, in which the cushion rubber is disposed at an end of the carcass ply or at an end of the belt, in which the side-wall rubber is disposed on an outer side in a tire-width direction of the cushion rubber, and in which the electronic unit is disposed between the cushion rubber, and the bead filler or the side-wall rubber.

A pneumatic tire 1 comprises a carcass 6 extending between bead cores of bead portions via a tread portion 2 and sidewall portions, and a belt layer 7 arranged on an outer side in a tire radial direction of the carcass 6 and inside of the tread portion 2. The pneumatic tire 1 further comprises a damping rubber body 30 arranged between the carcass 6 and the belt layer 7, and a noise damper 20 arranged on an inner cavity surface of the tread portion 2. A width W1 in a tire axial direction of the damping rubber body 30 is in a range of from 60% to 130% of a width W2 in the tire axial direction of the belt layer 7, and a water absorption rate of the noise damper 20 is in a range of from 10% to 25%.

A pneumatic tire of the present disclosure comprises a resin-coated belt, a base ring that comes in contact with a tire widthwise outer end of the resin-coated belt is provided on a tire radial inside of the resin-coated belt, a tire widthwise inner end of the base ring is located on an inner side of the tire widthwise outer end of the resin-coated belt in a tire width direction, while a tire widthwise outer end of the base ring is located on an outer side of the tire widthwise outer end of the resin-coated belt in the tire width direction, and the resin-coated belt has a rigidity changing portion where a rigidity changes from the tire widthwise inner side toward outer side in a tire widthwise region from the tire widthwise inner end of the base ring to the tire widthwise outer end of the resin-coated belt.
