PURPOSE: A pneumatic tire for a vehicle is provided to improve the productivity of a tire by using a bead core of one diameter regardless of the number of the carcass and forming a mono-fly type tire and a two-fly type tire with one device and setting. CONSTITUTION: A pneumatic tire for a vehicle comprises a tread section(1), a side wall section(2) and a bead section(3). The end portions of carcasses(41,42) are combined by penetrating through a bead core(30). Herein, the conjunction of the first carcass and the second carcass makes the carcasses combine with the bead core in the zigzag fashion between bead wires(31). Thus, a green tire is formed without separately making a half-completed bead core.
