A NOISE IMPROVING TREAD
Abstract:
A tire having a contact face of a width TW is provided. The contact face is intended to come into contact with ground during rolling. The tread is provided with at least one groove of a depth D provided with a wear indicating means that extends generally in a circumferential orientation and opens to the contact face. The tread comprises a center region and a pair of shoulder regions that are positioned on two axial sides of the center region. The shoulder regions each comprise a shoulder rubber layer of a thickness ts made of a shoulder rubber composition different from a rubber composition constituting the tread. A shear storage modulus G′ of the shoulder rubber composition measured at 23° C., 10 Hz and 10% of strain is less than or equal to 1.0 MPa.
