Abstract Method for manufacturing a tyre for vehicle wheels, of the type suitable for travelling on icy and/or snowy roads, comprising a tread band having an external surface containing a plurality of metal studs partially projecting from said external surface, comprising the steps of: manufacturing a green tyre; inserting and retaining said studs into specific seats provided in a vulcanization mould; inserting said green tyre into said mould; closing said mould; vulcanizing said green tyre, opening said mould to extract the cured tyre. Said seats are provided with a degree of clearance allowing the cured tyre to be extracted from the mould, at the opening of the latter, without interferring with said sectors and said studs to maintain their substantially perpendicular arrangement with respect to the external surface of the tread band.
