ABSTRACT:
A radial ply pneumatic tire (10) has carcass plies (13-15) reinforced by textile cords and folded axially around a pair of axially spaced bead cores (11,12) and a belt structure (30; 330) comprising at least two layers (32-34; 332-334) made of spirally wound strips. The spirally wound strips are reinforced by cords consisting at least in part of aramid yarns. Between each pair of neighboring layers (332-334) of spirally wound strips, a ply (340,341) reinforced by textile cords is interposed. Such a belt structure is more specifically suitable for an aircraft tire.
