摘要： A motorcycle tyre has a tread band (8) comprising a plurality of grooves that form a tread pattern including a module (T) replicated along a circumferential direction of the tyre (1) and having a predetermined circumferential length (C1). The module (T) comprises a pair of circumferential grooves (20) arranged on opposite sides with respect to the equatorial plane (X-X) of the tyre (1). Such circumferential grooves (20) extend along the circumferential direction of the tyre (1) for only part of said predetermined circumferential length (C1) and define between them a central portion (A) of tread band (8) having a void to solid ratio substantially equal to zero and a predetermined axial width (A1). The module (T) further comprises a plurality of transversal grooves (30, 31, 32, 33) arranged on opposite sides with respect to the equatorial plane (X-X) at a distance from said equatorial plane (X-X) greater than that of said circumferential grooves (20) and a pair of first lateral annular portions (B) axially arranged between said circumferential grooves (20) and said plurality of pairs of transversal grooves (30, 31, 32, 33), each of said first lateral annular portions (B) comprising, in a position axially adjacent to the respective circumferential groove (20), a respective part (B1) of tread band having a circumferential length at least equal to that of said circumferential grooves (20) and a void to solid ratio substantially equal to zero. The tyre (1) has a curvature ratio lower than about 0.32.

摘要： FIG. 1 is a top, front, right perspective view of a first embodiment of a tire, showing our new design, it being understood that the tread pattern is repeated uniformly throughout the circumference of the tire;
FIG. 2 is a front elevation view thereof;
FIG. 3 is a rear elevation view thereof;
FIG. 4 is a left side view thereof;
FIG. 5 is a right side view thereof;
FIG. 6 is an enlarged front perspective portion of the tire, as indicated by the bracketed portion in FIG. 1;
FIG. 7 is a top, front, right perspective view of a second embodiment of a tire, showing our new design, it being understood that the tread pattern is repeated uniformly throughout the circumference of the tire;
FIG. 8 is a front elevation view thereof;
FIG. 9 is a rear elevation view thereof;
FIG. 10 is a left side view thereof;
FIG. 11 is a right side view thereof; and,
FIG. 12 is an enlarged front perspective portion of the tire, as indicated by the bracketed portion in FIG. 7.
The portions depicted in broken lines of uneven length define the unclaimed boundary of the claimed design. The portions in broken lines of even length depict portions of the tire that form no part of the claimed design.

摘要： Motorcycles tyre, comprising: a radial carcass structure (2); a belt structure (6) applied in radially outer position with respect to the radial carcass structure (2); a tread band (8) applied in radially outer position with respect to the belt structure (6). The tyre (1) has a curvature ratio (f/C) greater than or equal to about 0.25. The tread band (8) comprises: a plurality of blocks (14) mutually spaced so as to define a tread pattern with a void/solid ratio (1−Sb/St) comprised between about 25% and about 50%; transverse grooves (11) placed in succession along the circumferential extension of the tyre (1) and each substantially extending over the entire axial width of the tread band (8). Each transverse groove (11) substantially extends along an axial direction. Two successive transverse grooves (11) circumferentially delimit an assembly (12) of blocks (14) placed in succession over the entire axial width of the tread band (8). Circumferential grooves (13) delimit the blocks (14) of an assembly (12). A ratio between a circumferential length (LI) of the blocks (14) and a width (L2) of the transverse grooves (11) is equal to or greater than about 2.
