发明名称 Pneumatic radial tire having an excellent side-cut resistant property
摘要 A pneumatic radial tire having an excellent side-cut resistant property is disclosed. The radial tire comprises at least one extensible and compressible rubberized side portion reinforcing layer arranged at that area of a side portion of the tire which is inclusive of at least maximum cross-section position of the carcass and each containing a reinforcing element embedded therein and composed of helically formed filaments or at least 2 bundles each formed by merely assembling together the helically formed filaments without twisting at random. The helically formed filament is formed of a material having a tensile breaking strength of at least 140 kg/mm2. The reinforcing element has an elongation at tensile breaking strength which is at least 1.2 times larger than that of a metal cord of a radial carcass.
