摘要

Studded tyre (10) the tread (20) of which comprises a first part (201) in contact with the ground and a second part (202) arranged radially on the inside of the first part, and at least one stud (30) projecting from the tread (20) and the head (70) of which is entirely anchored in the second part (202) of the tread (20), in which the complex modulus G (0°C) of the rubber compound of which the first part (201) of the tread (20) is formed is less than 1.5 MPa and in which the complex modulus G of the rubber compound of which the second part (202) of the tread (20) is made changes as a function of temperature such that G (5°C) is greater than or equal to 5 MPa and G*(20°C) is less than or equal to 0.5-G*(5°C).
