description The invention describes a process for manufacturing a tyre (1 ) for vehicle wheels comprising a tread band (7) at a radially outer position with respect to an inner tyre component (2, 6) of tyre (1 ) having at least one electrically conductive surface (6a). The process comprises forming an electrically conductive layer (7a) in the thickness of the tread band (7) between portions (7b, 7e) of the tread band (7) arranged at an axially contiguous position and formed by depositing at least one continuous elongated element of green elastomeric material according to contiguous circumferential coils (10). The electrically conductive layer (7a) comprises an electrically conductive material comprising at least one carbon black having a BET surface area, measured in accordance with standard ASTM D 6556-16, of at least 300 m2/g and an OAN (Oil Absorption Number) absorption value, measured in accordance with standard ASTM D2414-16, equal to or greater than 200 (ml oil/100 g carbon black).
