Abstract
A pneumatic tire (10) comprising a pair of annular beads (12,12') spaced from one another with a liner (20) extending between the tire beads. A reinforcement ply (24) and a barrier ply (26) are provided extending between the beads and a circumferentially inextensible belt assembly (28) is positioned in the crown region (30) of the tire. The reinforcement ply has parallel cords (27) of aromatic polyamide material or cables of steel and the barrier ply is made from a material having a ply modulus of elasticity substantially less than that of the reinforcement ply. The parallel cords or cables of the barruier ply preferably are at an angle (.alpha.) different than the angle (.beta.) of the parallel cords or cables of the reinforcement ply.
