Abstract

A tyre (100) for a motor vehicle with a low rolling resistance, said tyre comprising at least: a tread band (109), a rubber-coated carcass ply (101), whose opposite lateral edges are associated with respective right-hand and left-hand bead wires (102), each bead wire (102) being incorporated in a respective bead (103), a belt structure (106) applied along the circumferential extension of said rubber-coated carcass ply (101) and right-hand and left-hand sidewalls (108) applied on the outside of said rubber-coated carcass ply (101) and extending, in an axially external position, from the respective bead (103) to the respective end of the belt structure (106), said carcass ply (106) being coated by a rubber mixture having E' at 70 DEG C </= 5.0 MPa and E'' at 70 DEG C </= 0.50 MPa, and said sidewalls (108) being formed by a rubber mixture having E' at 70 DEG C >/= 3.5 MPa and E'' at 70 DEG C </= 0.50 MPa.
