RADIAL TYRE WITH AN OBLIQUELY LAP-WELDED CARCASS PLY

摘要

A radial tyre having at least one side wall and a carcass reinforcement consisting of at least one ply (20) reinforced by substantially radial parallel yarns (24), and comprising at least one lap weld (21) formed by overlapping two ends (22, 23) or adjacent portions of said ply. The general direction (D2) of the lap weld in said side wall is oblique relative to the direction (D1) of the radial yarns (24). Said radial tyre is particularly suitable for private cars or vans where the carcass reinforcement comprises a single radial ply, and the radial yarns (24) are, in particular, made from polyester and especially from polyethylene terephthalate. Compared with prior art radial tyres, said tyre has side walls with an enhanced outward appearance.
