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.
