    摘要： A motorcycle tyre includes a tread portion including a crown portion that is a region of 50% of a tread development width centered on a tyre equator, a first shoulder portion that is an outer region of the crown portion, and first lateral grooves. Each lateral groove includes a first groove portion in the crown portion, a second groove portion in the first shoulder portion, and a third groove portion connecting the first and second groove portions. A groove depth and a groove width of the third groove portion are respectively smaller than groove depths and groove widths of the first groove portion and the second groove portion, respectively. More than 80% of a tyre axial length of the third groove portion is in the first shoulder portion.

    摘要： Provided is a pneumatic tire used with a specified rotation direction, including a tread, a pair of sidewalls extending continuously from the tread inward in a tire radial direction, a pair of beads continuous with the sidewalls inward in the tire radial direction, and at least one ridge on a buttress surface. The buttress surface extends from a tread edge of a tread surface formed on the tread to the sidewall. The ridge extends from a sidewall side of the buttress surface towards the tread edge and terminates before reaching the tread edge. The ridge includes a steeply inclined surface, having a high gradient with respect to the buttress surface, inclined forwards in the rotation direction, and a moderately inclined surface, having a more moderate gradient than the steeply inclined surface, inclined backwards in the rotation direction.

    摘要： The invention relates to vehicle tires comprising a tread which is separated into profile positives by ridges, such as circumferential ridges (3, 3'), diagonal ridges, and the like. At least one profile positive is equipped with ridges (4) which extend locally in the profile positive without opening into other ridges. The ridges (4) consist of two ridge portions (5, 6) which run in the shape of a V relative to each other and which together form an acute angle (a) of 20° to 35° and are arranged substantially in the tread transverse direction. One ridge portion (5) has an extension length (l
    i ) which is longer than that of the other ridge portion (6) by two to three and a half times, and the ridge portion (5) with the longer extension length (1
    1 ) is provided with a bevel (11) running at an angle (y) of 25° to 50° relative to the radial direction at the transition region between the ridge portion flank (10) on the inside with respect to the V-shaped progression and the profile outer surface. The ridge base (7, 8) of each ridge portion (5, 6) continually widens towards the free end of each ridge portion (5, 6) and terminates at the outer surface of the tread.

    摘要： Provided is a pneumatic motorcycle tire in which, without compromising the stability during running, other performances such as light-weight are improved. Provided is a pneumatic motorcycle tire which comprises a tread portion 1, and side wall portions 2 and bead portions 3 extending from both sides of the tread portion, and whose rotation direction when the tire is mounted on a vehicle is designated. A tire tread is provided with a bent main groove composed of: a first groove 11 extending toward the designated tire rotation direction inclined outside in the tread width direction in a contact region during straight running; a second groove 12 extending from the end portion of the first groove in the reverse rotation direction of the designated tire rotation direction toward the reverse rotation direction of the designated tire rotation direction inclined outside in the tire width direction; and a third groove 13 extending from the end portion of the second groove in the reverse rotation direction of the designated tire rotation direction toward the reverse rotation direction of the designated tire rotation direction inclined outside in the tire width direction, and the bent main groove is formed such that an inclination angle ¸ 3 with respect to the tire circumferential direction of the third groove is larger than an inclination angle ¸ 2 with respect to the tire circumferential direction of the second groove.
