Abstract: A tire has a block pattern. The block pattern includes a plurality of linked block pairs. Each linked block pair includes two blocks 28 and a tie bar 30 interposed between the two blocks 28 and linking the two blocks 28 together. The tie bar 30 has a toe end 40 having a height equal to or smaller than a height of the blocks 28 and a heel end 38 having a height smaller than the height of the toe end 40.

Abstract: A motorcycle tyre for off-road includes a tread portion including a bottom surface and connected bodies. The block connected bodies each include blocks protruding from the bottom surface and tie-bars protruding from the bottom surface with a height smaller than that of the blocks to connect the blocks with one another. The block connected bodies include a first connected body whose blocks and tie-bars are arranged so as to surround the bottom surface at least partially. The first connected body includes a first end block located on a first end in a longitudinal direction of the first connected body and a second end block located on a second end in the longitudinal direction of the first connected body. The first end block and the second end block are adjacent with one another, and no tie-bar connecting the first end block and the second end block is provided.

Abstract: A tyre for running on rough terrain includes a tread portion. The tread portion includes a crown region, middle regions, and shoulder regions. The crown region is provided with a plurality of crown blocks. The middle regions are provided with a plurality of middle blocks. The shoulder regions are provided with a plurality of shoulder blocks. Each of the middle blocks is connected with at least one of the crown blocks by a crown tie bar and connected with at least one of the shoulder blocks by a shoulder tie bar. A land ratio of the shoulder regions is 90% or more and 115% or less of a land ratio of the crown region.

Abstract: Provided is a tire for a motorcycle for uneven ground traveling capable of continuously exhibiting good grip performance. The tire for a motorcycle for uneven ground traveling includes a tread part on which plural crown blocks are formed, and at least one of the crown block has a wheel tread, a first side surface, a first edge arranged between the wheel tread and the first side surface, a concave part that opens on the wheel tread and the first side surface, and a second edge arranged between the wheel tread and the concave part. The wheel tread has at least one external corner part in which an angle between the first edge and the second edge is an acute angle.

Abstract: A tyre for vehicle wheels having a tread pattern includes: a) two circumferential grooves, which define a first and a second shoulder region, and one central region; b) a plurality of asymmetric transverse grooves having a substantially “V” shape, which extend for the whole width of the tread, including an alternate sequence of a first and a second asymmetric transverse groove defining an alternate sequence of a first and a second asymmetric module; and c) a plurality of lateral transverse grooves, which includes one first lateral transverse groove extending for the whole width of the first shoulder region and for a portion of the central region of the first asymmetric modules, and one second lateral transverse groove extending for the whole width of the second shoulder region and for a portion of the central region of the second asymmetric modules.

Abstract: The purpose of the present invention is to provide a motorcycle tire for uneven ground travel for which the sticking of dirt to block grooves can be effectively prevented. Provided is a motorcycle tire for uneven ground travel in which a tread portion has a block pattern in which a plurality of blocks are provided. The blocks include, at the tread surface, at least one grooved block which has a block groove which is substantially C-shaped in plan view. The block groove has a pair of first groove portions that mutually extend in the same direction from the edge of the tread surface, and a second groove portion that links the first groove portions. The groove width W2 of the second groove portion is larger than the groove width W1 of the first groove portions, or the groove depth d2 of the second groove portion is larger than the groove depth d1 of the first groove portions.

Abstract: To provide a motorized two-wheeled vehicle tire for traveling on uneven terrain, the block durability performance of which has been improved; and a tire vulcanization mold capable of molding said tire. A motorized two-wheeled vehicle tire for traveling on uneven terrain wherein multiple blocks are provided on the tread at intervals in the tire circumference direction. Recesses are provided on the bottom surfaces of the grooves. Multiple recesses are provided at intervals in the axial direction of the tire. Spew, which was drawn up into the vent holes of the mold during vulcanization molding, or removal marks thereof are provided between each recess and the block that is adjacent in the tire circumference direction.
