PROBLEM TO BE SOLVED: To provide a technique by which both prevalence of fuel-efficient cars and improvement in stack performance in snowfall areas of fuel-efficient cars can be achieved by exerting sufficient stack performance even though the fuel-efficiency cars are two-wheel cars.SOLUTION: In the pneumatic tire, a spike pin insertion hole for driving a spike pin is provided in at least either one of a shoulder part and a side part. The mold for tire vulcanization is used in manufacturing a pneumatic tire, which comprises tread segments divided in plural numbers and a pair of side plates, where a mold pin for forming a spike pin insertion hole is provided in the vicinity of a dividing position where the tread segments match with the side plates.SELECTED DRAWING: Figure 4

    【課題】2輪駆動の低燃費車であっても十分なスタック性を発揮させることにより、低燃費車の普及と低燃費車の降雪地区におけるスタック性の改善の双方を共に解決することができる技術を提供する。【解決手段】ショルダー部およびサイド部の少なくとも一方に、スパイクピン打ち込み用のスパイクピン挿入孔が設けられている空気入りタイヤ。空気入りタイヤの製造に用いられるタイヤ加硫用金型であって、複数に分割されたトレッドセグメントと、一対のサイドプレートとを備えており、前記トレッドセグメントと前記サイドプレートとが合致する割り位置近傍にスパイクピン挿入孔形成用のモールドピンが設けられているタイヤ加硫用金型。【選択図】図4
