The invention relates to a method for producing a self-sealing pneumatic vehicle tyre, comprising a belt package (2) and a tread (1) as well as an air-tight inner layer (4) arranged radially inside, wherein the self-sealing of the pneumatic vehicle tyre is obtained by a central sealing ply (5) which is subsequently attached radially inside after the vulcanization of the pneumatic vehicle tyre, wherein the central sealing ply (5) has the width of the belt package (2) and is arranged in the projection thereof, and has a cross-section, which is formed in the cross-sectional plane containing the tyre axis, with a surface (5a) running in the axial direction in parallel to the belt package and a surface (5b) running in the radial direction. In the method, the central sealing ply (5) is coated by applying at least one suspension with a rotating spray disc or a spray gun, wherein the suspension contains at least one alkali salt of at least one fatty acid and/or at least one alkaline earth metal salt of at least one fatty acid.
