FIELD: machine building.
SUBSTANCE: invention relates to automotive industry. Studded tire (10) tread (20) includes first part (201) in contact with soil and second part (202), arranged radially inside relative to first part, and at least one stud (30) projecting outward from tread (20). Stud head (70) is completely fixed in tread (20) second part (202). Complex modulus G* (0 °C) of first rubber composition, which forms tread (20) first part (201), is less than 1.5 MPa. Complex modulus G* of rubber composition, forming tread (20) second part (202), varies with temperature so that G* (5 °C) is equal to or more than 5 MPa, and G* (20 °C) is less than or equal to 0.5G* (5 °C).
EFFECT: technical result is improved tire adhesion on ice at its reduced impact on asphalt.
