    摘要： It is an object to further improve the durability of bead portions in a pneumatic tire in which a carcass ply is turned up around bead cores. In a carcass (13), between first sections (13A) in which an inter-cord distance between a body portion and turn-back portions gradually decreases outward in a tire radial direction and second sections (13B) in which the inter-cord distance gradually increases, there are disposed first distance-invariant sections (13C) in which the turn-back portions (14B) are brought closer to the body portion (14A) that becomes a substantial bending neutral axis and in which the inter-cord distance is constant, so compressive force acting on the cords of the turn-back portions (14B) can be reduced. By disposing the first distance-invariant sections (13C) between the first sections (13A) and the second sections (13B), the direction of the cords of the turn-back portions (14B) is not suddenly changed, so it becomes difficult for stress to concentrate in the rubber between the cords of the turn-back portions (14B) and the cords of the body portion (14A) at the time of collapsing deformation of bead portions 12, and the durability of the bead portions (12) further improves.

    摘要： A tire includes a tread, a pair of beads, a carcass, and a band. The tread includes a large number of blocks which stand substantially outward in a radial direction. The carcass includes a carcass ply which is turned up around each bead. The carcass ply includes a main portion which extends from an equator plane toward each bead; and a pair of turned-up portions which extend from the main portion substantially outward in the radial direction. The band includes a band cord which is helically wound along a circumferential direction. An end portion of the turned-up portion and an end portion of the band overlap each other at an inner side, in the radial direction, of the tread. In the tire, a position of an end of the turned-up portion varies in the circumferential direction. The tire is excellent in handling stability and durability.

    摘要： A pneumatic tire and a method of fabricating a pneumatic tire are disclosed herein. The pneumatic tire includes a tread (10), sidewalls (20), and a carcass (103) including at least one carcass ply. One or more bead wire codes (105, 108) formed by stacking and arranging bead wires in a plurality of layers are formed on one or both sides of the carcass ply. One or more bead filler films (106, 107) are placed between the bead wire codes (105, 108). An end of the carcass ply (103) is wrapped around at least one bead wire code (105, 108). The wrap-around end (Tu) of the carcass ply (103) is disposed between neighboring bead wire codes (105) and (108) or beside the axially outermost bead wire code.

    摘要： The present invention provides a pneumatic tire 1, comprising: a carcass ply including a main body portion 11a extending across respective bead cores 9 and turn-up portions 11b each turned up around the bead cores 9 from the main body portion 11a; a bead filler 13; and a side rubber 5a, wherein: a tip portion on the outer side in the tire radial direction of the outer end 13a of the bead filler 13, of each of the turned-up portions 11b, extends to a position of at least 5 mm distance from the outer end 13a of the bead filler with maintaining distance of 1 mm or less between the main body portion 11a and itself; a turn-up end 11c is disposed on the inner side in the tire widthwise direction than a neutral axis of bending of a bead portion 7 and a corresponding sidewall portion 5 and at 10%-40% height of a tire cross sectional height SH of the tire; and the side rubber 5a, disposed on the outer side in the tire widthwise direction of the main body portion 11a and each turn-up portion 11b, covers the turn-up end 11c and constitutes a part of an outer surface of the tire.
