The invention relates to a self-sealing vehicle tyre comprising a belt package (2), a tread (1) arranged radially above the belt package (2), and an air-tight inner layer (4) arranged radially inside, wherein the self-sealing of the vehicle tyre is obtained via a sealing material layer (5a) subsequently attached radially inside after the vulcanisation of the vehicle tyre, wherein the sealing material layer (5) is substantially the width of the belt package (2) and is arranged substantially in the projection thereof, and has a cross-section, formed in the cross-sectional plane containing the tyre axis, with a surface (5a) running in the axial direction substantially in parallel to the belt package, and a surface (5b) running substantially in the radial direction. At least the surface of the sealing material layer (5a) running in the axial direction substantially parallel to the belt package comprises a coating (6) which contains sand. According to the method, the sealing material layer is at least covered with sand.
