Provided are: a stud capable of improving noise performance and stud detachment resistance; and a tire provided with the stud. In a stud (P) having a body section (10) embedded in the tread section of a tire, a head section (11) protruding from the tip side of the body section (10), and a flange section (12) disposed on the base end side of the body section (10), the cross-sectional area of the body section (10) in a plane orthogonal to the central axis (X) thereof varies along the central axis (X) of the body section (10). The cross-sectional area (Sa) at the maximum width position of the torso section (10) and the cross-sectional area (Sb) at the topmost position of the torso section (10) satisfy the relationship 0.30 < = Sb/Sa < = 0.80. In a tire (T), studs (P) are disposed on a tread portion (21).

    提供能够改善噪声性能及耐脱钉性的防滑钉及具备该防滑钉的轮胎。在具有埋设于轮胎的胎面部的躯干部(10)、从该躯干部(10)的顶端侧突出的头部(11)及配置于躯干部(10)的基端侧的凸缘部(12)的防滑钉(P)中,躯干部(10)的与其中心轴(X)正交的平面中的截面积沿着该躯干部(10)的中心轴(X)变化,躯干部(10)的最大宽度位置处的截面积Sa与躯干部(10)的最顶端位置处的截面积Sb满足0.30≤Sb/Sa≤0.80的关系。在轮胎(T)中,防滑钉(P)配置于胎面部(21)。
