Studded winter tire

A method for manufacturing a studded pneumatic tire, the method comprising

• producing an annular carcass by
• providing a first ply material, the first ply material extending in a longitudinal direction, having a first width in a transversal direction perpendicular to the longitudinal direction, and comprising first cords extending in a first direction forming a first angle of at most 10 degrees with the transversal direction, wherein the first cords comprise aramid, aramid content of the first cords being at least 45 wt. % of total weight of the first cords,
• winding at least a layer of the first ply material onto a carcass drum such that the transversal direction is parallel to the axis of rotation of the carcass drum, thereby forming a cylindrical carcass preform,
• arranging two cables to the cylindrical carcass preform, and
• expanding the preform, thereby forming the annular carcass,
• forming a preassembly of belts and a tread comprising
• at least one metal belt,
• an underlayer,
• a cap layer, and
• an intermediate layer, arranged, at least partially, between the underlayer and the cap layer, wherein hardness of the intermediate layer is at least 10% greater than hardness of the underlayer, determined at 22° C. as Shore A hardness, and
• the underlayer is harder than the intermediate layer, determined at −25° C. as Shore A hardness,
• arranging the preassembly of belts and a tread onto the annular carcass to form a preform,
• vulcanizing the preform, and
• installing studs,
• wherein the intermediate layer is configured to support a body of a stud together with the cap layer.
