Radial tire excellent in durability for bead part

摘要: PURPOSE:To prevent the occurrence of permanent set in a bead core, slipping and separation at carcass ply end, by reinforcing inside outside tire part with an independent reinforced layer separate manner. CONSTITUTION:A supporting 6 goes along inner surface 1, while its height (h) from base line B extends up to within 40% maximum H line, prevents outward tilt due load 5 and, what is more, improves problem core 3 as well resistance. And, made be higher modulus than terminal protector 7 being arranged outer rewinding 1 design.
