摘要： A method for manufacturing a motorcycle tire comprises: building a raw tire main body, building a breaker, sticking the breaker, and building a band. The building of the breaker comprises: moving two cylindrical support rings to operating positions, swelling the raw tire main body to have its crown portion protruding from the support rings through a gap therebetween, and winding a breaker ply material on the support rings to form a cylindrical breaker ply whose inner surface is adhered to the raw tire main body. The sticking of the breaker comprises: expanding a profiled deck to swell the raw tire main body into a second swollen state, and turning down both edge portions of the breaker while being supported by the profiled deck. The building of the band comprises: spirally winding a tape on the curved breaker ply while being supported by the profiled deck.

摘要： In a tire 2, each of sidewalls 6 includes a first layer 36 disposed axially outward of a corresponding one of beads 8, and a second layer 38 extending outward from the first layer 36 in a radial direction. When Pc represents a position of an axially outer end of an interface between a carcass 10 and the sidewall 6, an outer end 40 of the first layer 36 is disposed radially inward of the position Pc. A hardness H1 of the first layer 36 is greater than a hardness H2 of the second layer 38. A ratio (H2/H1) of the hardness H2 to the hardness H1 is preferably not less than 0.70 and preferably not greater than 0.95.

摘要： This manufacturing method of a pneumatic tire having a tread reinforcing layer reduces tire mass while maintaining the durability performance of the tire. A tread reinforcing layer formation step includes a winding step for winding belt-shape plies around an approximately cylindrical winding surface. The winding step involves: a first winding step in which, with the side edges of the belt-shape plies spaced from one another, said belt-shape plies are spirally wound from a first end located on one side of the tire in the axial direction, to a second end located on the other side of the tire in the axial direction; and a second winding step in which, with the side edges of the belt-shape plies spaced from one another, said belt-shape plies are spirally wound from the second end to the first end in the direction opposite that in the first winding step. A lattice-form tread reinforcing layer is formed that has gaps substantially rhombic in shape and bounded by the belt-shape plies.

摘要： A pneumatic tire has a tread reinforcing layer comprising a net structure formed from a tape of rubber coated reinforcing cord(s). The net structure comprises first oblique segments and second oblique segments of the tape which intersect with each other, forming interspaces therebetween. The first oblique segment has a first axial outer part in which the angle of the tape with respect to the tire circumferential direction decreases toward one end in the tire axial direction of the net structure. The second oblique segment has a second axial outer part in which the angle of the tape with respect to the tire circumferential direction decreases toward the above-said one end of the net structure. The first axial outside part is connected to the second axial outside part directly or through a circumferential segment of the tape.

摘要： A motorcycle tire set S includes a front wheel tire S1 and a rear wheel tire S2 each provided with a plurality of inclined grooves 3. Each inclined groove 3 includes a first portion 11 extending in a crown region Cr, a second portion 12 extending in a shoulder region Sh, and a third portion 13 connecting the first portion 11 and the second portion 12. The third portion 13 has a smaller groove width than the first portion 11 and the second portion 12. The first portion 11, the second portion 12, and the third portion 13 are inclined in the same direction with respect to a tire circumferential direction. Each inclined groove 3 of the rear wheel tire S2 comes into contact with the ground from the first portion 11 toward the third portion 13 based on a tire rotation direction R.

摘要： A pneumatic tire includes a tread portion and a pair of sidewall portions extending inward in a tire radial direction from both edges of the tread portion. At least one of the sidewall portions is provided with a vent line and a recessed portion adjacent to each other in the tire radial direction. The vent line protrudes from a sidewall outer surface and extends in a tire circumferential direction. The recessed portion is recessed from the sidewall outer surface at a first depth. A serration pattern, in which a plurality of ridges extending in the tire radial direction are arranged in the tire circumferential direction, is formed in the recessed portion. Each of heights of the ridges is smaller than the first depth.
