摘要： Provided is a tire exhibiting improved wear resistance, partial wear resistance, and traction performance on the wet road surface. The tire has block land portion arrays 5 defined on a tread portion 1. Between two block land portion arrays 5 located adjacent to each other while sandwiching a circumferential groove 2, a block land portions 4 constituting the block land portion arrays are arrange so as to be positionally displaced from each other, and a groove portion 6 located between the block land portions adjacent in the tire width direction extends obliquely with respect to tire width direction and the tire circumferential direction. At this time, a distance d2 between the block land portions adjacent in the tire width direction is shorter than a distance d1 between the block land portions adjacent in the circumferential direction. In the block land portion arrays 5 adjacent in the tire width direction, an inclined angle α of a side wall 9 of the block land portion 4 located on the groove portion 6 side with respect to the tire circumferential direction is larger than an inclined angle β of the other side wall 10 located on the opposite side to said groove portion 6 with respect to the tire circumferential direction.

摘要： An object the present invention is to provide a tire having a rib-like land portion and sipes provided therein, in which wear resistance has been enhanced by optimizing the shape of the sipes, while good fraction performance on a wet road surface is maintained. The tire has, in a tread portion, at least one row of rib-like land portion and sipes provided in the rib-like land portion. Further, depth of each sipe at least at one end portion thereof on the shoulder side is smaller than depth of the sipe at the remaining portions thereof.

摘要： An object of the invention is to provide a tire and a method of producing the tire, in which tire breakage of a groove fence in vulcanization molding and generation of cracks at a groove bottom can be suppressed, noise is relatively low and uneven wear is less likely to occur. At least one of a groove wall 71 surface of the circumferential groove 222 and a side wall 43 surface of a stepped land portion 41 is provided with a groove fence 51 which are formed in the extending direction of the circumferential groove at a predetermined intervals therebetween such that the groove fence protrudes in the groove widthwise direction of the circumferential groove. The groove fence 51 is characterized in that: it has a thin wall portion 53 having a shape in which a portion 61 thereof on the side of the groove bottom of the circumferential groove has been notched in a section orthogonal to the circumferential groove 22; and an angle formed by a notched face 53a of the thin wall portion 53 with respect to the at least one of the wall surfaces 71 provided with the groove fence 51 is set at 70° or smaller.
