The present invention provides a pneumatic tire with a bead part having enhanced stiffness, and more specifically, a pneumatic tire with a bead part having enhanced stiffness, which has a structure without a turn-up structure of an end of a carcass while having at least one bead core to increase stiffness of the bead part and a sidewall. The pneumatic tire is formed by a bead core (11) formed by bead wire cords (10) rolled in several layers, bead fillers (12) in at least two rows, which are attached to the bead core (11), a carcass fly (3) arranged between the bead fillers (12) and the bead core (11) to have a linear structure without a turn-up structure, and left and right bead fillers (12a, 12b) having the bead core (11) formed by the bead wire cords (10) and arranged on both sides of the carcass fly (3). The bead wire cords (10) of the left and right bead fillers (12a, 12b) have a structure having a diameter becoming smaller toward the upside from a bead base (14). COPYRIGHT KIPO 2017 ...
