Beschreibung
Zusammenfassung:	A pneumatic radial tire having an improved bead portion reinforcing construction is disclosed. The radial tire comprises a bead portion reinforcing band disposed along the bead portion formed by folding the ply of the carcass body around the bead ring. The bead portion reinforcing band comprises at least one chipper layer. The chipper is composed of a reinforcing element embedded in rubber and formed of 1 to 50 helically formed filaments. The reinforcing element has a modulus of elasticity of 0.029x104 kg/mm2 to 1.60x104 kg/mm2 and is inclined at a given angle with respect to the ply cords of the carcass body so as to make the chipper as a whole extensible and rigid.
