A tire having a plurality of studs spaced apart in a ground-contact surface of a tread section, the tire comprising: a plurality of circumferential stud rows whose positions are different from each other in a tire width direction and each of which is constituted by a plurality of studs which are six or more than six and sequentially arranged along a tire circumferential direction, wherein when in each of the circumferential stud rows, the number of studs is expressed by T, a stud interval of the plurality of studs in the tire circumferential direction by L(n), wherein n is an integer from 1 to T, and an average value of the stud interval L(n) by La, each stud interval L(n) satisfies a condition of 0.4×La≤L(n)≤1.7×La, and one or more specific stud intervals each satisfying a condition of 1.1×La≤L(n)≤1.7×La are included among the plurality of stud intervals of each circumferential stud row, and are not continuous along the tire circumferential direction, the ground-contact surface of the tread section is divided into: two center areas (7A, 7B) each being located between a center line in the tire width direction and a division line spaced apart by a quarter distance (H/4) a tread ground-contact width from the center line toward an outer side in the tire width direction; and two shoulder areas (8A, 8B) each being located between a respective division line and a tread ground-contact end on an outer side of the respective division line in the tire width direction, characterized in that when an average value of the number of studs of each circumferential stud row located in the center areas (7A, 7B) is expressed by Nc, wherein the average value Nc is calculated by dividing the total number of studs of all the circumferential stud rows located in the center areas (7A, 7B) by the number of the circumferential stud rows located in the center areas (7A, 7B), and an average value of the number of studs of each circumferential stud row located in the shoulder areas (8A, 8B) is expressed by Ns, wherein the average value Ns is calculated by dividing the total number of studs of all the circumferential stud rows located in the shoulder areas (8A, 8B) by the number of the circumferential stud rows located in the shoulder areas (8A, 8B), the average values Nc, Ns satisfy a condition of Ns>Nc. a plurality of circumferential stud rows whose positions are different from each other in a tire width direction and each of which is constituted by a plurality of studs which are six or more than six and sequentially arranged along a tire circumferential direction, wherein when in each of the circumferential stud rows, the number of studs is expressed by T, a stud interval of the plurality of studs in the tire circumferential direction by L(n), wherein n is an integer from 1 to T, and an average value of the stud interval L(n) by La, each stud interval L(n) satisfies a condition of 0.4×La≤L(n)≤1.7×La, and one or more specific stud intervals each satisfying a condition of 1.1×La≤L(n)≤1.7×La are included among the plurality of stud intervals of each circumferential stud row, and are not continuous along the tire circumferential direction, the ground-contact surface of the tread section is divided into: two center areas (7A, 7B) each being located between a center line in the tire width direction and a division line spaced apart by a quarter distance (H/4) a tread ground-contact width from the center line toward an outer side in the tire width direction; and two shoulder areas (8A, 8B) each being located between a respective division line and a tread ground-contact end on an outer side of the respective division line in the tire width direction, characterized in that when an average value of the number of studs of each circumferential stud row located in the center areas (7A, 7B) is expressed by Nc, wherein the average value Nc is calculated by dividing the total number of studs of all the circumferential stud rows located in the center areas (7A, 7B) by the number of the circumferential stud rows located in the center areas (7A, 7B), and an average value of the number of studs of each circumferential stud row located in the shoulder areas (8A, 8B) is expressed by Ns, wherein the average value Ns is calculated by dividing the total number of studs of all the circumferential stud rows located in the shoulder areas (8A, 8B) by the number of the circumferential stud rows located in the shoulder areas (8A, 8B), the average values Nc, Ns satisfy a condition of Ns>Nc.
