PURPOSE: A pneumatic tire is provided to improve the endurance of the bead by restricting bending of the end of a bead filler and extending the height of the bead filler, and to enhance driving experience and steering stability by forming the bead with different materials. CONSTITUTION: A pneumatic tire is composed of a tread part, a side wall and a bead part. The bead part has a bead core(30) formed by assembling plural wires, and a bead filler(4) stacked in the upper part of the bead core. The bead filler is divided vertically, and a reinforcing member(5) is inserted between divided bead fillers. The reinforcing member is manufactured with arranging reinforcing cords, and the bead core is covered with the reinforcing member. The bead filler is formed with inserting the end of the reinforcing member between bead fillers. Failure is prevented in forming the tire with inserting the reinforcing member between bead fillers in assembling the bead filler with the bead core. A carcass is combined with a side wall firmly with restricting bending of the bead filler, and crack and separation are prevented.
