<p>A tyre for motor-vehicles is described the belt structure (3) of which has consecutively overlapped first and second belt strips (5, 6) and a pair of side straps (7) overlying the second belt strip (6) adjacent to the side edges (6a) of said second belt strip and each made up of at least one cord circumferentially wound in a plurality of coils to form two radially superposed layers of coils disposed in axial side by side relation. The first belt strip (5), located adjacent to the carcass structure (2), substantially has the same width as the tread band (4), and laterally projects from the second belt strip (6) radially overlapped therewith. The second belt strip (6) has side flaps (6b) projecting from the side straps (7) and spaced apart from the first belt strip (5) by a progressively growing measure away from the outer edges (7a) of the side straps themselves. These side straps axially project inwardly with respect to the position corresponding to the groove bottom of the axially outermost circumferential groove. <IMAGE></p> |
