Title: Method for manufacturing pneumatic tire and pneumatic tire
Inventor: MITSUYOSHI ISAO
IPC: B29D30/48
Filed: 2002-11-01
Abstract: <P>PROBLEM TO BE SOLVED: To provide a pneumatic tire which delays fault occurrence on a carcass and can enhance durability.  <P>SOLUTION: A green tire is formed of using a bead core 12 having a mono-strand portion 18 formed of winding a large diameter wire at the outside in a tire axle direction and a strand portion 20 formed of winding a small diameter wire at the inside in the tire axle direction, and is vulcanized. When tensile force acts to the carcass with an internal pressure during vulcanization, the bead core 12 is strongly pressed particularly at the inside in the tire axle direction and also at the inside portion in a diameter direction, the vicinity of a core surface is deformed along a carcass ply, and the carcass ply 16 results in a contact configuration close to face contact against the bead core 12. Since a cord in the carcass ply 16 creates no large distortion against a specific wire in the bead core 12 and creates only small distortion against a plurality of small diameter wires 24 respectively, a problem that the carcass ply 16 is damaged in an early stage can be avoided.  <P>COPYRIGHT: (C)2004,JPO
