A ratio H1/H2 of a height (H1) of an outer end (10e) in a tire radial direction of the first rubber portion 10 from a bead base line (BL) and a height (H2) of an outer end in the tire radial direction of each of the turned up portions (6b) from the bead base line (BL) is in a range of from 1.4 to 1.7.

Tire comprising carcass reinforcement (7) comprising turned-up carcass layers (71, 72) and non-turned-up carcass layers (73, 74), each turned-up carcass layer (71, 72) comprising main part (711, 721) wrapped, in each bead (4), from the inside of the tire towards the outside around bead wire (8) of diameter D, to form turn-up (712, 722) of which end (E1, E2) is positioned radially on the outside of radially outermost point E of bead wire (8) at a radial distance (a1, a2), each non-turned-up carcass layer (73, 74) having an end (E3, E4) which is positioned at radial distance (b3, b4) from the radially outermost point of E of bead wire (8), the radial distance (a1, a2) is at least equal to 0.5 times the section height H of the tire and the radial distance (b3, b4) is at most equal to diameter D of bead wire (8).

A pneumatic tire for a motorcycle includes a tread having a tread surface which makes contact with ground, a pair of beads each positioned on a radially inner side of the tread, a carcass bridging one of the beads and the other one of the beads, and a reinforcement layer laminated on the carcass on the radially inner side of the tread. Each of the beads includes a core and an apex extending from the core in a radially outward direction, and the apex of each of the beads has an outer edge positioned on a radially outer side of an edge of the tread surface.

Provided is a pneumatic tire having the structure where a carcass ply is wound around bead cores from the outside in the tire width direction to the inside in the tire width direction, and both end portions of an inner liner extend between beads and the carcass ply. A lightweight and highly rigid tire can be acquired. The tire can also enhance steering stability performance thereof. The pneumatic tire includes: a pair of left and right beads including bead cores 3a; a carcass ply extending between the bead cores; and an inner liner 4 disposed on an inner peripheral side of the carcass ply 5, wherein the carcass ply 5 is wound around the bead cores 3a from the outside in the tire width direction to the inside in the tire width direction, and both end portions of the inner liner 4 extend between the beads and the carcass ply.

A motorcycle tire that includes a carcass as a skeleton composed of at least one carcass ply extending toroidally between a pair of bead portions and folded and engaged around a pair of bead cores embedded in each of the pair of bead portions and a belt composed of at least one belt layer arranged on the outer side of the carcass in the tire radial direction. A flipper is arranged between the carcass and a bead core, which wraps the bead core from the inside in the tire radial direction, and the outer side end portion of the flipper in the tire width direction extends to the inside in the tire width direction from the end portion of the belt in the tire width direction.

A pneumatic tire includes a tread, sidewalls, clinches, beads, a carcass, and strips. Each bead includes a core, a first apex and a second apex, the carcass includes a carcass ply which is turned up around the core from the axially inner side toward outer side such that the carcass ply is divided into a main portion and a turn-up portion, each strip has radially inner edge positioned between the main and turn-up portions, the second apex is positioned between the turn-up portion and each clinch, each strip has outer edge positioned to correspond to or on inner side of a point of maximum width of the tire in radial direction, the second apex has outer edge positioned on radially inner side of the outer edge of each strip, and the second apex includes crosslinked rubber and has complex elastic modulus in range of from 60 MPa to 70 MPa.

[Object] A tire, for a two-wheeled automotive vehicle, which is excellent in ride comfort and steering stability, is provided.

[Solution] A tire 12 for a two-wheeled automotive vehicle includes a carcass 20 that is extended on and between one of beads 18 and the other of the beads 18 along inner sides of a tread 14 and sidewalls 16. The carcass 20 includes a first ply 34 and a second ply 36 that is layered outward of the first ply 34. The first ply 34 is turned up around the beads 18 from an inner side toward an outer side in an axial direction. By the turning-up, the first ply 34 includes a main portion 34a and turned-up portions 34b. The second ply 36 is turned back around the beads 18 from the outer side toward the inner side in the axial direction. By the turning-back, the second ply 36 includes a main portion 36a and turned-back portions 36b.

A pneumatic tire can include a carcass, a belt layer, and reinforcing rubber layers. Turned-up portions of a carcass ply each include a first portion located between a body portion and the belt layer, a second portion adjacent to each reinforcing rubber layer in a tire axial direction, on an outer side in a tire radial direction with respect to a rim flange of a standardized rim, and a third portion located between the first portion and the second portion. A length of the third portion is 0.8 to 1.4 times a sum (La+Lb) of a length La of the first portion and a length Lb of the second portion.

Pneumatic tyre having a toroidal carcass, which has a body ply that is partially folded onto itself and therefore having two lateral flaps; two annular beads, each of which is surrounded by the body ply and has a bead core and a bead filler; an annular tread; a pair of sidewalls; a pair of abrasion gum strips; an innerliner which is impermeable to air and is arranged within the body ply; and a transponder which is arranged between the body ply and the innerliner at a flap of the body ply and is arranged at a distance of less than 7 mm from an edge of the body ply.
