摘要： A tire with a tread reinforcing layer that includes a ply reinforcing structure formed by winding a cord-embedded rubber tape circumferentially of the tire. The ply reinforcing structure includes first oblique segments and second oblique segments which intersect with each other to form a mesh structure having rhombic spaces. The circumferential lengths of the rhombic spaces are less than ⅔ times the maximum circumferential length of the ground contacting patch of the tire in its normally loaded state.

摘要： A method for manufacturing a tire, the method includes arranging bead members onto a molding drum on axially both end sides thereof such that outer surfaces of bead reinforcing rubber components of the bead members have bent faces each having an inverse V-shaped manner protruding radially outwardly, winding a non-turn-up carcass ply on the molding drum such that axially both end portions of the non-turn-up carcass ply cover the respective bent faces, joining the axially both end portions of the non-turn-up carcass ply wound on the molding drum to the respective bent faces. The joining includes a first step for reforming each end portion of the non-turn-up carcass ply in an inverse V-shaped manner so as to be along a respective one of the bent faces, and a second step for pressing reformed end portions of the non-turn-up carcass ply onto the respective bent faces using respective press rollers.

摘要： In a tire 2 for a two-wheeled automotive vehicle, a carcass ply 24 is extended on and between one bead 8 and the other bead 8 along inner sides of a tread 4 and sidewalls 6, and includes a main portion 24a and turn-up portions 24b, which are formed by the carcass ply 24 being turned up around the beads 8 from an inner side toward an outer side in an axial direction. An outer end Pp of each turn-up portion 24b is positioned outward of a tread end Pe in a radial direction. A band 14 is positioned between a belt 12 and the tread 4, such that the band 14 covers the belt 12. An outer end P1 of an inner layer 28 layered over a carcass 10 and the outer end Pp of the turn-up portion 24b are positioned facing each other.

摘要： A motorcycle tire has a unidirectional tread pattern formed by a circumferentially extending center main groove, and main oblique grooves each with a branch groove. The main oblique groove has an axially inner end inside a zero-camber ground contacting width and an axially outer end outside the zero-camber ground contacting width. The axially outer end is positioned in a range between 0% and 20% of the developed half tread width from the tread edge. The branch groove is composed of a first inclined part extending from the main oblique groove at an angle θ with respect to the tire circumferential direction, and a second inclined part extending at an angle δ less than the angle θ. When the developed half tread width is axially equally divided into five portions, the land ratio of each of the five portions is 75% to 85%.
