摘要: In an apex 34 of a tire 2, a reinforcing portion 48 is located inward of a main body 46 in an axial direction. When a position on an outer surface of the tire 2 at which position a height from a BBL is 14 mm is defined as a first point P1 and a position on the outer surface of the tire 2 at which position a height from the BBL is 20 mm is defined as a second point P2, the reinforcing portion 48 overlaps the first point P1 and the second point P2 in a radial direction. A loss tangent of the reinforcing portion 48 is equal to a loss tangent of the main body 46 or less than the loss tangent. A hardness of the reinforcing portion 48 is equal to a hardness of the main body 46 or greater than the hardness.

摘要: Provided is a pneumatic tire by which productivity and handling stability are improved. A pneumatic tire comprises: a carcass that spans from a tread section, through a side wall section, and to a bead core of a bead section; a bead apex rubber that has a roughly triangular cross-sectional shape and extends in a tapered shape from the bead core toward the tire radial outer side; and a bead reinforcement material that is wound in a spiral shape around the bead apex rubber or a composite of the bead apex rubber and the bead core.

摘要: A pneumatic tyre having a carcass ply (6A) extending between bead portions (4) and including a topping rubber layer, the topping rubber layer (11i) facing the inside of the tyre being made of a butyl rubber compound containing at least 10 parts by weight of butyl rubber or butyl rubber derivative; and a belt (7) disposed radially outside the carcass in the tread portion (2), comprising at least one ply (7A) of monofilament cords (20) laid at an angle of from 10 to 40 degrees with respect to the circumferential direction of the tyre, each of the monofilament cords consisting of a single filament. The belt (7) further comprises one ply of multifilament cords (7b) or a second ply of monofilament cords (20). The height (Ha) of the bead apex can be reduced into a range of from 10 to 20 mm, and in this case, the carcass ply turnup portion (6b) extends radially outwardly beyond the radially outer end of the bead apex so as to adjoin the carcass ply main portion.

摘要: In a tire 2, a band 12 is disposed between a tread 4 and a carcass 10 in a radial direction, and is layered over the carcass 10. A first carcass ply 30 of the carcass 10 has a main portion 30a and turned-up portions 30b. A second carcass ply 32 of the carcass 10 is disposed outward of the main portion 30a of the first carcass ply 30 in the radial direction, and is extended on and between one of the beads 8 and the other of the beads 8. Ends P2 of the second carcass ply 32 are disposed between the beads 8 and the turned-up portions 30b, respectively, on outer side in the axial direction. Ends P1 of the turned-up portions 30b are disposed between the main portion 30a and the band 12. The turned-up portions 30b and the band 12 are layered over each other.

摘要: A pneumatic tire 2 includes a buttress reinforcing layer 22. A carcass 12 includes a first ply 38 and a second ply 40. The first ply 38 and the second ply 40 each have a main portion that is extended on and between beads 10 on both sides. The buttress reinforcing layer 22 extends along the first ply 38 and the second ply 40 between the first ply 38 and the second ply 40. An outer end 22a of the buttress reinforcing layer 22 is disposed inward of a shoulder region S of a tread 4 in a radial direction. An inner end 22b of the buttress reinforcing layer 22 is disposed at a maximum width position of the tire or disposed outward of the maximum width position of the tire in the radial direction.
