摘要：
A method for manufacturing a tread strip with shoulder cover strips for a pneumatic vehicle tire includes the step of continuously extruding a shoulder cover strip and calendering the shoulder cover strip to a desired thickness. The thus thickness-reduced cover strip is then applied to the tread strip. The shoulder cover strip is then cut to length in order to match a circumferential length of the tread strip for building a tire.
