The invention relates to a method of manufacturing a vehicle tire, the tread portion of which comprises a poorly conducting tread layer (21) that provides a ground contacting surface disposed in a radially outward part of the tread portion, and a conductive layer (24) arranged underneath the tread layer. The method comprises providing a layered assembly of tread layer rubber and conductive layer rubber, and forming the assembly in a mould (2) provided with a local recession (3A,3B) in the mould surface, such that part of the assembly flows into the recession (3A,3B) to form a protrusion comprising conductive layer rubber, and removing said protrusion to expose the conductive layer rubber. The invention also relates to a device used in carrying out the method. The invented tire has antistatic properties without compromising other performance characteristics.
