Tyre for a heavy-duty vehicle, this tyre comprising a tread (1) having a thickness E of wearable material and a tread surface (10) intended to come into contact with a roadway, this tread (1) having, on at least one raised element, a plurality of inclined sipes (5) extending into the thickness of the tread, these inclined sipes (5) having suitable widths such that they close up at least partially when they enter the contact patch in contact with the roadway. The tire being formed from a material having, −a tan(δ)max/(G*25%) ratio is at most equal to 0.065, in which tan(δ)max is the measurement, at 60° C., of the loss factor of the material of which the tread is made, and G*25% is the complex dynamic shear modulus, expressed in MPa, and—a deformation at break under tensile testing which is at least equal to 530%, this value being obtained at a temperature of 60° C.
