Abstract
A method for arranging stud pins in a pneumatic tire is a method for arranging stud pins in a tread portion at intervals in a tire width direction so as to form a plurality of rows. This method includes specifying an inner region, an intermediate region, and an outer region by virtually partitioning the tread portion into equal three parts from a center line extending in a tire circumferential direction to a ground contact end in the tire width direction outward. The method also includes arranging the stud pins such that among numbers of stud pins per row in the inner region, the intermediate region, and the outer region, the number in the outer region is the largest, the number in the intermediate region is the second largest, the number in intermediate region is the smallest.

A method for arranging stud pins in a tread portion at intervals in a tire width direction so as to form a plurality of rows, the method comprising:
- specifying an inner region, an intermediate region, and an outer region by virtually partitioning the tread portion into equal three parts from a center line extending in a tire circumferential direction to a ground contact end in the tire width direction outward, the equal three parts each having plural stud-pin rows extending in the tire circumferential direction;
- and
- arranging the stud pins such that among average numbers of stud pins per stud-pin row in the inner region, the intermediate region and the outer region, the number in the outer region is the largest, the number in the intermediate region is the second largest, and the number in the inner region is the smallest.
