Abstract

A tyre has a tread reinforcing breaker formed by at least two cross- laid plies 1, 2 of metal reinforcement cables and at least one edge ply, e.g. 3, formed by circumferentially extending reinforcement members. The or each edge ply may have a modulus greater than 5,000 daN/cm and may comprise reinforcement members of aromatic polyamide, or of a material with a large initial elongation under stress. The or each edge ply may be located radially outwardly of the cross-laid plies as shown or between these plies. The tyre may have a radial carcass and an aspect ratio less than 100%. <IMAGE>
