    Abstract: A pneumatic tire for heavy load enabling the co-existence of wet performance and uneven wear resistance performance is provided. The pneumatic tire for heavy load includes three circumferential main grooves 31 and 33 extending on a tread in the circumferential direction, and ribs 11 and 12 defined by these circumferential main grooves 31 and 33. The centerline of the center circumferential main grove 31 among the three circumferential main grooves is positioned on the equator line of the tread, and a thin rib-shaped uneven abrasion sacrificing part (BCR) 21 having a step in a clearance thereof from the surface of the tread is formed only in the center circumferential main groove 31.

    Abstract: A vehicle wheel tyre includes a carcass structure, a belt structure, and a tread. The tread includes four circumferential grooves and a plurality of transverse grooves that define at least five circumferential rows of blocks, each block approximating a polygon. The longitudinal sides of the blocks are inclined in the same direction at a predetermined angle to the equatorial plane of the tyre. The blocks of each row are circumferentially staggered relative to the blocks of the next row. The blocks of the central row include stiffening means. Profiles of the front sides of the blocks of the central row are the same as the profiles of the rear of the blocks of the central row rotated through 180°. The blocks of the shoulder rows are elastically linked to the blocks of the intermediate rows.

    Abstract: A pneumatic radial tire comprises a tread provided with a plurality of circumferential grooves extending in a circumferential direction of the tire, and plural rows of land portions defined between axially adjacent circumferential grooves and between each of edges of the tread and the adjacent main circumferential groove. That groove wall of at least the circumferential groove located nearest to at least one of the tread edges on a treading surface of the tread which is positioned on a side of the one of the tread edges is inclined to gradually increase a width of the groove toward the surface of the tread from a location spaced by 10-70% of a depth of the circumferential groove radially outwardly from a bottom thereof. The width of an opening of the circumferential groove to the surface of the tread is in a range of 3-18 mm.

    Abstract: A pneumatic tire for vehicles has a tread band provided with grooves which extend circumferentially about the tire. The grooves are formed by a series of substantially rectilinear sections which are disposed at a predetermined angle with the equatorial plane of the tire and intersect to impart a zig-zag arrangement to the grooves about the tire. The intersections between said groove sections are situated in planes parallel to the equatorial plane of the tire, and each tread surface portion between one of the parallel planes and a pair of adjacent sections of a groove is shaped so the distance at its points from the tire axis gradually decreases from the parallel plane toward the region in which the sections of the pair of adjacent sections intersect.
