The tread is provided with a plurality of grooves and/or a plurality of incisions. The tread also has rubber layers laminated in a radial orientation. One rubber layer has a cap rubber layer and a base rubber layer. A modulus G* of the rubber composition constituting the base rubber layer is no more than 2 MPa at −10° C. with imposed shear stress of 0.25 MPa and is at least 0.7 MPa at 40° C. with imposed shear stress of 0.70 MPa. A modulus G* of the rubber composition constituting the cap rubber layer is at least 1 MPa higher than the modulus G* of the the base rubber layer at −10° C. with imposed shear stress of 0.25 MPa and is less than the modulus G* of the rubber composition at 40° C. with imposed shear stress of 0.70 MPa.
