    摘要： A method for manufacturing a pneumatic tire includes: a step of winding carcass plies around a molding drum to mold a carcass, wherein the carcass has a joint portion in which ends of each of the carcass plies in a tire circumferential direction are overlapped with each other, the method further includes a step of pasting a rubber tape that covers at least a part of the joint portion after winding the carcass ply, and the rubber tape has: a central portion pasted to an outside of the joint portion and extending with a constant thickness along the tire circumferential direction; and tapered portions individually extending from both ends of the central portion in the tire circumferential direction along the tire circumferential direction while reducing a thickness of each of the tapered portions, and having tip ends with an angle of 45 degrees or less.

    摘要： The present invention aims at providing a pneumatic tire for a motorcycle, capable of improving steering stability and wear resistance in a turning situation with maintaining good turning performance achieved by a relatively wide auxiliary belt layer. Specifically, the present invention provides a pneumatic tire for a motorcycle, characterized in that: the auxiliary belt layer is sectioned into a middle area Am overlapping a region where the belt layer is provided and respective side areas As each extending beyond the region where the belt layer is provided; the cords in the middle area Am extend at an inclination angle θm in the range of 70° to 90° with respect to the tire circumferential direction; and the cords in each side area As extend, in at least a portion of the side area, at an inclination angle θs different from the inclination angle θm with respect to the tire circumferential direction.

    摘要： [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.

    摘要： The invention relates to a tire having at least one carcass reinforcement comprising reinforcers, surmounted radially on the outside by a crown reinforcement, itself radially on the inside of a tread, said crown reinforcement being made up of at least one layer of reinforcement elements, said tread being connected to two beads by way of two sidewalls, said beads being intended to come into contact with a rim flange having a rim flange top C, each bead having at least one circumferential reinforcement element, said carcass reinforcement comprising an end at each bead, the end of the carcass reinforcement being turned up once in an outward radial direction of the tire and about said bead wire, so as to form a turnup, then being folded in said radially inward direction so as to form a fold forming a radially external end and three adjacent parts along an axial axis made up of a central part, of an axially internal lateral part, and of an axially external lateral part.The tire is characterized in that the radially external end of the turnup is disposed between the rim flange top C and a point D, said points C and D being situated at the surface of the sidewall and disposed on either side of a point E situated on the sidewall corresponding to the nominal section width, said point D being disposed at a maximum radial length equal to 85% of the length present between the axial end S of the crown reinforcement and the rim flange top C.

    摘要： Disclosed is a pneumatic radial tire for a passenger car having ultra fine steel cords for a carcass ply in which adhesive force between a carcass ply layer and a side wall or a rim flange rubber adjacent to a turn up portion on an outside and a stiffness of the rim flange rubber are larger than a bending stiffness of the carcass ply layer so as to improve durability of a bead part while reducing poor air inletting generated at a carcass turn up portion.

    摘要： A pneumatic radial aircraft tire is described having a B/A ranging between 60-70%. The tire may further optionally include a tire bead portion having a Ra/Fr1 relationship which ranges from about 1 to about 2.1. The tire may further optionally include a SW/TS ratio which ranges from about 0.1 to about 0.5, wherein SW is the chafer gauge at area A, TS is the total sidewall rubber gauge at area A, wherein A is defined as the region in the sidewall that has a lower radial endpoint defined by the point of contact between the flange and the tire at inflated, unloaded condition, and an upper radial endpoint AH defined by the tire wheel flange point of contact when the tire is at inflated, and at 200% rated load.
