摘要： A tire for motor vehicles includes a belt structure (3) 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 the second belt strip. Each side strip (7) is 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 spacing which progressively grows with distance 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.

摘要： A carcass ply is applied around an outer surface of a building drum according to an application diameter larger than the fitting diameter of a tire. Coaxially engaged around each of the end flaps is an annular anchoring structure defining the fitting diameter. A pair of sidewalls is manufactured by laying of a continuous elongated element in the form of approached coils on the carcass sleeve. An outer sleeve, including at least one belt structure possibly associated with a tread band, is coaxially centered around the carcass sleeve. Through axial approaching of two halves forming the building drum, the carcass sleeve is shaped into a toroidal configuration to determine application of same against a radially internal surface of the outer sleeve.
