摘要： The invention relates to a tyre comprising a crown reinforcement formed by at least two working crown layers (41, 43) of reinforcing elements and at least one layer (42) of circumferential reinforcing elements. According to the invention, the tread includes at least one longitudinal notch (8) and at least one transverse notch (10), the depth of said at least one longitudinal notch and said at least one transverse notch, measured on a new tyre, being greater than or equal to 40% of the thickness of the tread. The ratio of the width of said longitudinal notches measured at the base thereof to the width of same measured at the surface of the tread is strictly greater than 1.2, while the ratio of the width of said at least one transverse notch measured at the base thereof to the width of same measured at the surface of the tread on a new tyre is strictly greater than 1. The tensile modulus of elasticity at 10% elongation of at least one skim coat of at least one working crown layer is greater than 9 MPa, and the maximum tan(δ) value, denoted tan(δ)max, of the at least one skim coat of at least one working crown layer is less than 0.100.

摘要： A winter tyre has a tread pattern comprising two particularly wide longitudinal grooves (12, 13) so as to create in a footprint area working zones of the tread band - a central zone (LI) and two shoulder zones (L2, L3) - which are substantially independent of each other; the central zone (LI) occupies a substantial part of the tread band and comprises a plurality of circumferentially consecutive blocks provided with sipes (40) arranged in an oblique direction with respect to the equatorial plane of the tyre; the inclination of the sipes (40) formed in circumferentially adjacent blocks alternates in the circumferential direction, forming sequences of inclined and counter-inclined sipes.

摘要： A tire tread formed from a rubber composition having a functionalized SBR and a BR that is reinforced with between 95 phr and 125 phr of a silica filler and includes a plasticizing system to adjust the glass transition temperature to be between −30° C. and −15° C. and the dynamic modulus G* at 60° C. to be between 0.9 MPa and 1.15 MPa. The tread includes central tread blocks having an average central tread block length of between 6.5 mm and 10 mm and shoulder tread blocks having an average shoulder tread block length of between 10 mm and 20 mm. Furthermore the tread is limited to being between 6.5 mm and 7.7 mm thick. In particular embodiments the rubber composition may be just the functionalized SBR.
