A tire comprises at least one bead having an axial width at the seat D comprises at least one main circumferential reinforcing element of which the radially innermost point is at a radial distance Z and at an axial distance Y from the radially innermost point of the bead, and such that Y/D is at least equal to 0.5 and Z/D is at most equal to 0.4. This same bead comprises at least one bead layer surrounding the bead filler rubber such that its axially outermost end is radially on the outside of the end of the carcass layer and it also comprises at least one additional circumferential reinforcing element, radially on the inside of the radially outermost point of the main circumferential reinforcing element.

A bead member for a tire, including: a bead wire; a first bead filler that is in contact with the bead wire directly or via another layer and is arranged in a region including at least a region at an outer side of the bead wire in a tire radial direction; and a second bead filler that is in contact with the first bead filler directly or via another layer and is arranged in a region including at least a region at an outer side of the first bead filler in the tire radial direction, the first bead filler including a resin A, the second bead filler including a resin B, and the resin B having a melting point higher than that of the resin A.

A bead member includes an annular bead filler made of a resin, and a deformation facilitating portion configured to facilitate an axial deformation is provided at a portion of the bead filler in a radial direction.

A method for forming a composite apex, the method comprising the steps of: forming a coextruded strip of a first compound and a second compound, wherein the second compound is a compound different than the first compound, wherein the apex is formed from winding the coextruded strip while varying the ratio of the first compound to the second compound.

A run-flat tire comprises a tread portion, sidewall portions, bead portions, and a carcass ply extending between the bead portions. The sidewall portions are each provided therein with a sidewall reinforcing rubber layer having a crescent-shaped cross sectional shape and disposed on the axially inside of the carcass ply. The sidewall portions are each provided in the axially outer surface thereof with a rim protector which projects radially outward most on the radially outside of the radially inner edge of the sidewall reinforcing rubber layer. The bead portions are each provided therein with an axially inside core and an axially outside core between which each radially inner edge portion of the carcass ply is secured. When measured along a normal line drawn normally to the carcass ply from an apex of the rim protector, the thickness of the sidewall reinforcing rubber layer is in a range of from 29% to 35% of the thickness of the tire.

A pneumatic tyre includes a tread portion, two axially spaced sidewall portions extending radially inwardly from the tread portion, at least one of the sidewall portions being provided with a side protector that protrudes axially outwardly and having an inner end located radially outwardly of a tyre-maximum-width position, and two axially spaced bead portions connected to radially inward of the respective sidewall portions. Each bead portion includes a bead apex rubber having an outer end in the tyre radial direction being located radially inwardly of the tyre-maximum-width position. A radial length of a tyre inner region from a bead baseline to the outer end of each bead apex rubber is in a range of from 0.8 to 1.2 times a radial length of a tyre outer region from a radially outermost position of the tread portion to the inner end of the side protector.

A pneumatic tire includes a bead core, a bead filler located outside in a tire radial direction of the bead core, a carcass ply laid over between bead cores and bead fillers which are provided in a pair in the tire width direction respectively, a belt wound on an outside in the tire radial direction of the carcass ply, a tread portion located outside in the tire radial direction of the belt, and a sidewall portion located outside in the tire width direction of the carcass ply. A thickness dimension of the tire side portion is set to increase as proceeding from a tire maximum width position toward an outside in the tire radial direction.

Provided is a pneumatic tire comprising a pair of bead fillers located on opposite sides of a tire equatorial plane, comprising resin materials, respectively, and formed asymmetrically with each other relative to the tire equatorial plane.

A tire includes a pair of beads having a bead filler which extends to an outer side in the tire-radial direction of a bead core, and a carcass ply which extends from one bead to another bead and is folded back around the bead core, in which an electronic component is embedded in an area range of 10 mm to an inner side in the tire-radial direction from a tire-radial direction outside end of the bead filler.
