Abstract: 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.

Abstract: A carcass (14) includes two carcass plies (16) and (17). A carcass cord is provided at an angle of 65 to 88 degrees with respect to the circumferential direction of a tire (10). The carcass ply (16) is wound upon a bead (13) from an inside toward an outside in a radial direction. The carcass ply (16) overlaps symmetrically in a crown portion (18). The carcass plies (16) and (17) are fastened and reinforced in the radial direction by means of a band (15). An overlapping dimension (Wo) of the carcass ply (16) is set to be 30% to 90% of a tread width (W). The carcass ply (17) is extended to have a height (h) along a sidewall (12). The height (h) is set to be 20% of a height (H) of the sidewall (12) or more.

Abstract: A motorcycle tire which comprises a carcass (6) extending between tire bead portions (4), and a belt (7) disposed radially outside the carcass, wherein the belt (7) is formed by spirally winding at least two reinforcing members (11 and 12) having different elastic moduli so that the lower elastic modulus reinforcing member (11) and the higher elastic modulus reinforcing member (12) serially appear in the widthwise direction of the belt.
