    摘要: A tire (22) according to the present invention includes a pair of beads (28), a carcass (30) and a belt (32). An absolute value of an angle formed by a carcass cord of the carcass (30) with respect to a circumferential direction is equal to or greater than 60 degrees and is equal to or smaller than 90 degrees. A belt ply (50) of the belt (32) is constituted by a center portion (52) and a pair of side portions (54) positioned on an outside in an axial direction of the center portion (52). A ratio of a perimeter of the center portion (52) to that of the side portion (54) is equal to or higher than 10% and is equal to or lower than 50%. The center portion (52) includes a center cord which is spirally wound in a substantially circumferential direction and is formed of steel. The side portion (54) includes a side cord which is spirally wound in the substantially circumferential direction and is formed by an aramid fiber.

    摘要: The invention relates to a tyre comprising: at least one carcass-type reinforcing structure which is anchored to each side of the tyre in a bead; a reinforcing crown ply; and sidewalls which are assembled radially outwards to a running tread. The carcass-type reinforcing structure extends circumferentially from the bead towards said sidewall and is discontinuous over at least one portion of the tyre crown. The aforementioned reinforcing crown ply comprises (i) at least one primary reinforcing structure which more or less covers the entire width of the crown and (ii) at least one series of circumferential reinforcing elements which also more or less cover the entire width of the crown. The series of circumferential reinforcing elements comprises a portion of lateral circumferential reinforcing elements (46), which are disposed radially and externally in relation to the primary reinforcing structures, and a portion of median circumferential reinforcing elements (44) which are disposed radially and internally in relation to said primary reinforcing structures.

    摘要: A medium truck tire (10) and more specifically a super single truck tire (10) includes cut belt plies (22,23,25) reinforced with steel cords which make an angle of about 20 degrees with respect to the equatorial plane. Disposed in embedded fashion between two of the belt plies (23,25) is a pair of substantially full spiral helically wound overlays (24).

    摘要: A radial tire, especially a heavy−duty radial tire enhanced in durability, wherein a ratio W2/W1 between a belt layer width W1 on the carcass side of a small−inclination belt layer provided over 0.25−0.50 times the tread width in a tire width direction and the remaining belt layer width W2 is set to range from 1.1 to 1.3, whereby cracks, causing separation at a belt width end, are prevented from growing or progressing in the vicinity of the terminal of a cord used for a belt cord, and shortcomings in reinforcing a radial tire tread are overcome.
