摘要： A pneumatic tire comprises a tread portion provided with blocks divided by main grooves extending continuously in the tire circumferential direction, and axial grooves connecting between the main grooves. The blocks include a siped block (21, 21, 22). The siped block (21, 21, 22) is provided with a first sipe (30) extending in the tire axial direction across the block (21, 21, 22), and second sipes (38) respectively disposed in regions subdivided by the first sipe (30). Each of the second sipes (38) is a closed sipe whose both ends are closed, and the maximum depth of the second sipe (38) is less than the maximum depth of the first sipe (30).

摘要： A pneumatic tire comprises, in a tread surface: at least two circumferential main grooves continuously extending in a tire circumferential direction; and at least one rib-like land portion each defined by two adjacent circumferential main grooves from among the at least two circumferential main grooves. The rib-like land portion has: a circumferential sipe including a circumferential sipe portion extending in the tire circumferential direction; and a both-end closed sipe having both ends terminating within the rib-like land portion. When a land portion width of the rib-like land portion is evenly divided by three where a region at a center in a tire width direction is a center region and regions on both sides of the center region in the tire width direction are side regions, the circumferential sipe portion is located only in the center region, and the both-end closed sipe is located in any of the side regions.

摘要： The invention relates to a tyre tread comprising at least one elongate block (3) made from rubber-like material, of width W and length L, where L>>W, said elongate block extending along a circumferential direction (X) when the tread (1) is mounted on the tyre. The elongate block (3) comprises a contact surface (5) intended to come into contact with a road surface, and a first side wall (7) and a second side wall (9) defining said contact surface (5). The elongate block (3) also comprises a plurality of cutouts (11a, 11b) that open onto the contact surface (5) of the elongate block, said cutouts (11a, 11b) extending along an oblique direction from the first side wall (7) in the direction of the second side wall (9) as far as the cutout ends (13a, 13b). For at least one cutout (11a) that opens onto the first side wall (7) its cutout end (13a) does not open onto the second side wall (9), and when the aforementioned cutout (11a) reaches its cutout end (13a) another cutout (11b) starts from the first side wall (7) on the same circumferential level on the elongate block (3). The cutouts (11a, 11b) are incisions.

摘要： The disclosure concerns a tread band for a tire, said tread band having two sides with a predetermined distance D between these two sides and a centre. Indeed the tread band has a plurality of blocks, each block extending continuously in a curved manner to one side of the tread band towards the centre of this tread band with no groove separating this block in different parts, the block following a certain curvature C. All or part of the blocks of the plurality of blocks include a main sipe extending in the block and following the same curvature C, this sipe separating the block in two half parts.
