Abstract
The invention relates to a studded tire the tread of which comprises a first part in contact with the ground and a second part placed radially to the inside of the first part, and at least one stud protruding from the tread, and the head of the stud being entirely anchored in the second part of the tread, in which the complex modulus G*(0° C.) of the rubber composition forming the first part of the tread is less than 1.5 MPa and in which the complex modulus G* of the rubber composition forming the second part of the tread varies with temperature such that G*(5° C.) is equal to or greater than 5 MPa and G*(20° C.) is less than or equal to 0.5 G*(5° C.).
