A motorcycle tire includes a tread portion, a pair of sidewall portions, a pair of bead portions, a toroidal carcass extending between the pair of bead portions, and a belt layer and a band layer disposed outwardly in the tire radial direction of the carcass in the tread portion. The carcass includes a plurality of carcass cords. The band layer includes a jointless band ply having a band cord wound spirally at an angle equal to or less than 5 degrees with respect to a tire circumferential direction. The belt layer includes a plurality of belt cords arranged in a direction intersecting with the carcass cords. The belt cords intersect with the carcass cords at an intersection angle θc in a tread crown region, and intersect with the carcass cords at an intersection angle θs in tread shoulder regions, and the intersection angle θc is greater than the intersection angle θs.

Bicycle tyre (100) which comprises a pair of bead cores (8), a carcass structure (2) turned around the pair of bead cores (8) and a tread band (4) radially outer to the carcass structure (2); at each bead core (8) being provided: an elastomeric material filler (12) which extends in a radial direction for a first length (HI) starting from the bead core (8), a loop (15) interposed between the carcass structure (2) and the elastomeric material filler (12), turned around the bead core (8) so as to define a first flap (15a) axially outer to the elastomeric material filler (12) and a second flap (15b) axially inner to the elastomeric material filler (12), wherein the first flap (15a) extends in a radial direction for a second length (H2) and the second flap (15b) extends in a radial direction for a third length (H3); preferably, the second (H2) and third (H3) lengths are less than or equal to the first length (H1).

A tire pair includes a front tire 2 and a rear tire 52. The front tire 2 includes a pair of beads 18, a carcass 10 extending on and between a first bead 18 and a second bead 18, a tread 4 located outward of the carcass 10 in a radial direction, and a band 14 located between the tread 4 and the carcass 10 in the radial direction. The carcass 10 includes a large number of carcass cords 30 aligned with each other and each tilted relative to an equator plane. The band 14 includes a band cord 34 extending substantially in a circumferential direction. A ratio (Jf/Jr) of a bending stiffness Jf of the band cord 34 of the front tire 2 to a bending stiffness Jr of a band cord 84 of the rear tire 52 is not less than 0.0 and less than 0.7.

Provided is a pneumatic tire including a belt layer. When the tread region indicates a region corresponding to a belt width of the belt layer and the side region indicates a region inward of a tire radial direction with respect to a tire maximum width position, the carcass cords forming the carcass layer are inclined with respect to the tire radial direction in the tread region, and at the same time, extend along the tire radial direction in the side region. The carcass cords forming the carcass layer and belt cords forming the belt layer cross with each other in the tread region.

A tire of the “bias belted” type for a motorbike comprises: a tread (2) connected by two sidewalls (3) to two beads (4). A crown reinforcement (5) is radially on the inside of the tread (2) and comprises at least one crown layer (51, 52), such a crown layer (51, 52) comprising mutually parallel reinforcers. A carcass reinforcement (6) is radially on the inside of the crown reinforcement (5) and comprises at least two carcass layers (61, 62, 63), each comprising mutually parallel reinforcers, and crossed from one carcass layer to the next. The reinforcers of each crown layer (51, 52) form, with the circumferential direction (XX′), an angle between 15° and 25° in the equatorial plane (XZ), and the reinforcers of each carcass layer (61, 62, 63) form, with the circumferential direction (XX′), an angle between 40° and 50° in the equatorial plane (XZ).
