摘要： A block (1) for a pneumatic tire has a substantially rectangular contour as a whole, a ratio of the width (W) of the block to that of a tread in a range of 0.10 to 0.30, and a ratio of the length (L) of the block to the width of the tread in a range of 0.075 to 0.250. At least a wall (2) of the block on a stepping-in side is inclined in a range of 10° to 45° relative to a meridian line (Y-Y) of the tire. The surface of the block is provided with a single sipe (4) opening at widthwise opposite side edges of the block. The widthwise projected length b of that portion of the sipe which is located on the stepping-in side while not overlapping the other portion is set at not more than 0.35 a in which a is the entire length of the sipe projected in the width direction of the tread.

摘要： A shoulder block (1) includes a thin groove (2) formed substantially at the center in the circumferential direction of a tread, transverse sipes (4) circumferentially spaced from the thin groove (2), and at least one circumferential sipe (3) extending substantially circumferentially without intersecting the thin groove (2) or the transverse sipes (3), in such a manner that a circumferential component of the circumferential sipe is greater than its transverse component. The thin groove (2) extends widthwise of the tread, and has a length substantially equal to the width of the block. The transverse sipe (4) extends widthwise of the tread, and opens at the side wall (1a) of the block on the side of the center of the tread. Opening widths of the thin groove and the transverse and circumferential sipes are not more than 3.0 mm. The difference h₁-h₂ between a depth h₁ of the thin groove and a depth h₂ of the transverse sipe is 0.75h₁ ≧ h₁ - h₂ ≧ 0.3h₁, and depths H and h₂ of the circumferential sipe and the transverse sipe are such that H ≧ h₂, and the circumferential entire length L of the circumferential sipe and an average length ℓ of the block are such that L ≧ 0.5ℓ.

摘要： A pneumatic tire (10) has a block pattern in which at least three block rows each comprised of a plurality of blocks separated from each other in the circumferential direction of the tire are arranged in a tread portion of the tire so as to be separate from each other in the widthwise direction of the tire. In this tread pattern, the blocks of the mutually adjoining block rows have a circumferential length L (mm) of 10.5≦ L≦45 and are shifted between these block rows in the circumferential direction of the tire, and each of these blocks is divided by at least one sipe (44) having a depth h (mm) of 5≦h≦15, or further a block portion of each block (20) in a central block row (14) among these block rows divided by a sipe is connected to a block portion of each block (28) in the adjoining block row (22) through a platform (46) arranged in a groove (16) separating these block rows (20,22) from each other in the widthwise direction of the tire.
