摘要： A heavy duty pneumatic radial tire is disclosed, which comprises a carcass composed of at least one rubberized ply containing cords arranged substantially in a radial plane of the tire and a belt superimposed about a crown portion of the carcass just beneath a tread and composed of at least three rubberized belt plies. In this tire, metal cords of a first belt ply nearest to the carcass among the above belt plies are arranged at an angle of 25.degree.-50.degree. without crossing with metal cords of a second belt ply near the carcass next to the first belt ply with respect to a central circumferential line of the tire, and metal cords of the second belt ply and a third belt ply near the carcass next to the second belt ply, a tensile strength of each of which being 1.5-2 times that of the metal cord of the first belt ply, are arranged at an angle of 10.degree.-30.degree. and smaller than the cord angle of the first belt ply with crossing with each other between these two belt plies with respect to the central circumferential line of the tire.

摘要： A heavy duty pneumatic tire is disclosed, which has a tread pattern formed in a tread divided into a plurality of lands by a plurality of longitudinal grooves extending circumferentially of the tread, among which each of a first land in at least a side edge region of the tread and a second land adjacent thereto has an arrangement of blocks defined by transverse grooves arranged at a substantially equal interval in the circumferential direction of the tread. In this tread pattern, each block of the first land is arranged in zigzag form opposite to two adjoining blocks of the second land, the opposed groove walls of the longitudinal groove defining the first and second lands have a minimum distance corresponding to not more than 3% of the tread width, and the remaining longitudinal groove(s) located in a center of the tread or sandwiching the central land of the tread has a groove width corresponding to 4-10% of the tread width.

摘要翻译： 公开了一种重型充气轮胎，其具有胎面花纹，胎面花纹形成在通过沿胎面圆周延伸的多个纵向槽分割成多个胎面的胎面中，其中，在至少一个侧缘区域 胎面和与其相邻的第二台肩具有在胎面的圆周方向上以基本相等的间隔布置的横向槽限定的块的布置。 在该胎面花纹中，第一花纹的每个块以与第二花纹的两个相邻的块相对的Z字形排列，限定第一和第二幅面的纵向槽的相对的槽壁具有对应于不大于3的最小距离 占胎面宽度的百分比，并且位于胎面中心的剩余纵向沟槽或者夹着胎面的中心部分具有对应于胎面宽度的4-10％的槽宽度。
