摘要： A pneumatic tire improved in on-ice performance and on-snow performance in good balance. The pneumatic tire includes a tread portion extending in a tire circumferential direction and forming a ring shape, a pair of sidewall portions on both sides of the tread portion, respectively, and a pair of bead portions on inner sides of the sidewall portions in a tire radial direction, respectively. The tread portion includes a plurality of longitudinal grooves extending in the tire circumferential direction and a plurality of lateral grooves extending in a tire width direction. The longitudinal and lateral grooves define a plurality of block rows each including a plurality of blocks. Each of the plurality of blocks included in at least one of the block rows includes at least three closed grooves including at least one first closed groove and at least one second closed groove.

摘要： A pneumatic tire has a good balance between on-ice and on-snow performances. The tire includes a tread portion having longitudinal and lateral grooves defining block rows. Each block in the block rows includes sipes. A length of each block in the first and second block rows is not less than 1.5 times and not more than 2.5 times a length of each third block row block. A width of each second block row block is larger than a width of each first block row block. The lateral grooves defining the first and second block row blocks are offset in the tire circumferential direction by not less than 0.2 times and not more than 0.8 times the length of each first block row block. The lateral grooves defining the second and third block row blocks communicate with each other while inclining in the same direction.

摘要： A pneumatic tire including rib-like land portions partitioned by a plurality of main grooves extending in a tire circumferential direction and/or block-like land portions partitioned by the plurality of main grooves and a plurality of lug grooves intersecting the main grooves in a tread surface. A plurality of protrusions are provided on a surface of the land portions, and at least two types of the protrusions, having different surface areas, are provided. Moreover, at least a majority of the protrusions adjacent to a small protrusion having a relatively small surface area are large protrusions having a relatively large surface area.

摘要： A pneumatic tire including, on a tread surface, rib-like land portions partitioned by a plurality of main grooves and/or a plurality of block-like land portions partitioned by lug grooves extending in a tire width direction, wherein sipes or small holes are provided in the land portions, multiple protrusions are disposed having a height that is less than a depth of the sipes or small holes, and the multiple protrusions are disposed so as to form a shape wherein a flow path width increases at a flow path convergence point where flow paths formed in a mesh-like shape between the protrusions converge from at least three directions, and a ratio of an area of the multiple protrusions to an area of a block-like land portion is 0.5 or greater and 0.9 or less.

摘要： In the sand core 10, the tar reducing agent is included in at least the second coating layer 13, which is the outermost layer, of the coating layers 12 and 13. Thus, the tar, which may be generated from the core body 11 and the coating layers 12 and 13 which are positioned thereinside, can be decomposed into low molecular gases (carbon monoxide, carbon dioxide, water, and the like) by heat of the molten metal. As a result, generation of the tar from the sand core 10 to the outside can be prevented. In this case, since the layer which includes the tar reducing agent is the second coating layer 13 which directly contacts the molten metal, the second coating layer 13 can directly receive the heat of the molten metal, and the tar generation prevention effects can be thereby remarkably obtained. Therefore, generation of defects in cast products which may be caused by clogging in the gas drain can be prevented, and structures of the gas drain of the die and the surroundings thereof can be simplified.
