Estimating the term…
The invention relates to a self-sealing pneumatic vehicle tire having a belt package (2), a tread (1) arranged radially above the belt package (2) and an airtight inner layer (4) arranged radially on the inside, wherein the self-sealing of the pneumatic vehicle tire is obtained via a sealant layer (5) subsequently applied radially on the inside after the vulcanization of the pneumatic vehicle tire, wherein the sealant layer (5) has essentially the width of the belt package (2) and is arranged essentially in the projection thereof and has a cross section which is formed in a cross-sectional plane including the tire axis and has a surface (5a) running essentially parallel to the belt package in axial direction and a surface (5b) running essentially in radial direction. It is a feature of the invention that at least the surface of the sealant layer (5a) running essentially parallel to the belt package in axial direction has a circumferential coating (6) that contains at least elastomer particles. In the method of the invention, the sealant layer is coated at least with elastomer particles.
