The tyre (1), having a carcass reinforcing structure (2) anchored in its beads (3), side walls (4) and a curved tread surface (5), has crown reinforcing layers (6, 7) with their outer edges lying inside the carcass reinforcement at the tangential points (A, B) between the curved tread surface and lines (100, 101) perpendicular to the tyre's axis. The crown reinforcement consists of at least one continuous filament with central sections lying at an angle of between 10 and 80 degrees to the circumferential plane. The tyre also has a series of circumferential crown reinforcing cords (8) spaced at a variable pitch across the tyre so that they are closer together at the centre of the crown than its edges. |
