Abrégé

The present invention is intended to reduce the vibration noise of a tire having a plurality of studs while maintaining the ice-performance during the rotation of the tire. A plurality of circumferential stud rows (6) is constituted by a plurality of studs (5) which are six or more than six and sequentially arranged along a tire circumferential direction S. In each of the circumferential stud rows (6), T is the number of studs (5), L(n) is a stud interval, and La is the average value of the stud interval L(n). The stud interval L(n) satisfies a condition of 0.4×La‰¤L(n)‰¤1.7×La. One or more specific stud intervals each satisfying a condition of 1.1×La‰¤L(n)‰¤1.7×Laare included in a plurality of stud intervals of the circumferential stud row (6) and are not continuous along the tire circumferential direction.
