Abstract: A tire includes a sipe, on a surface of a tread of a tire, extending across a tire equator from one side to another side of the tire equator. An end of the sipe on at least the one side is located at a tread edge or near the tread edge, and an inclination angle of the sipe relative to a width direction of the tread decreases from the tire equator towards the tread edge.

Abstract: In regions, divided by the tire equator, on both sides of the tread surface of a tire, the tire includes a grip area along the entire circumference of the tread, the grip area including a plurality of recessed lines, with a shape recessed toward an inner side of the tire from the outline of the tread surface, that extend from the tread edge side in a direction inclined relative to the tire equator and are arrayed in parallel, and a plurality of sipes that extend toward the tire equator in a direction inclined relative to the tire equator, starting in the grip area and terminating before the tire equator. The negative ratio in the grip area is higher than the negative ratio closer to the tire equator than the grip area.

Abstract: A tire includes a plurality of buffer recessed portions (40) compression-deformable in a tire radial direction that are arranged in a tire circumferential direction over an entire area in the tire circumferential direction on an outer surface of a buttress portion (12) connected to an end portion of a tread surface portion (11) of the tire in a tire width direction, in which in a plan view of the buttress portion, an opening peripheral edge of the buffer recessed portion has a hexagonal shape including six side portions (41, 42), and the buffer recessed portions adjacent to each other in the tire circumferential direction are arranged such that one of the six side portions of one of the buffer recessed portions faces one of the six side portions of the other of the buffer recessed portions in the tire circumferential direction.

Abstract: In a tire, a plurality of outer resonators (25) are formed in an outer land portion (28) partitioned by two outer main grooves (21, 22) and arranged in a tire circumferential direction, a plurality of inner resonators (26) are formed in an inner land portion (29) partitioned by two inner main grooves (23, 24) and arranged in the tire circumferential direction, the outer resonator includes a first vertical groove (31) which extend in the tire circumferential direction, and a first branch groove (32) and a second branch groove (33) which have an inner volume smaller than that of the first vertical groove, extend in the tire width direction from both end portions of the first vertical groove in the tire circumferential direction such that the first branch groove and the second branch groove extend in directions opposite to each other, and are respectively opened to the two outer main grooves, and the inner resonator includes a second vertical groove (36) which extends in the tire circumferential direction, and a

Abstract: A sole for a prosthetic leg is a sole which is attached to a ground contact region of the prosthetic leg with a road surface and includes a through hole at least on a partial region.
