The present invention relates to vehicle tires of the kind having a crown belt formed from at least one pair of plies made of cords which are orientated in directions which intersect at small angles, and having sidewalls each reinforced by at least one strong half-ply making up a carcass which is interrupted under the belt. The invention which consists in a combination of the following features:

Vehicle tires

A pneumatic tire of low cross-section of a height to width ratio equal to or less than 0.8, and which is suitable for use at high speed. The tire has a radial carcass and a crown belt interposed between the radial carcass and the tire tread for the width of the tread surface, the belt being formed from two main plies of unequal width composed of high modulus flexible cords which are orientated in opposite direction at small angles, one at least of the plies having its lateral edges folded over and flattened against the inner face of the belt. A third, narrower, belt ply is positioned on the outer face of the belt against the central part of the ply whose edges are folded. The width of the third ply is between the width of the narrower and unfolded ply and the width of the space between the edges of the wider folded ply.
