Abstract

Provided is a pneumatic tire having stud pins implanted in a road contact surface of a tread portion, the pneumatic tire being capable of improving the performance on ice while improving the ride comfort characteristics on dry road surfaces. In the pneumatic tire with stud pins (P) implanted in the road contact surface of a tread portion (1), a region defined between a pair of tire meridians arranged with a spacing of 1/4 of a ground contact length of the tire on a tire equator (CL) is defined as a band region (A), and a plurality of band regions (A) are arranged over the entire circumference of the tire while shifting an angle by one degree along the tire circumferential direction. Then, in all of the plurality of band regions (A), the number n of stud pins (P) ineluded in each of the band regions (A) is 4.0% or less of the total number N of stud pins (P) in the entire circumference of the tire, and in 2/3 or more of the plurality of band regions (A), the number n of stud pins included in the band region (A) is 2.0% or more of the total number N.
