<p><P>PROBLEM TO BE SOLVED: To provide a pneumatic tire for reducing rolling resistance on the basis of a structure of a bead core. <P>SOLUTION: In the pneumatic tire having a bead core 5 in a bead part, the bead core 5 is formed by annularly winding a bead wire S having a substantially circular cross section so that a plurality of peripheral parts S1 of the wire may be aligned in a tire width direction and also overlap each other in a tire radial direction, and a ratio of a cross sectional height H to the maximum width W of the bead core 5 is set within 0.24 to 0.46, and the maximum width W of the bead core 5 is set within 4.5 to 10.0 mm. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
