The invention relates to a method for producing a tread (20), comprising the steps: extruding the tread (20), which has an outer side (22) and an inner side (24), opposite the outer side (22), and a carrying region (26) made of a carrying region rubber material and a guide strip (28) made of a guide strip rubber material, wherein the guide strip (28) extends from the outside (22) to the inside (24) and a specific electrical guide strip resistance (W28) of the guide strip rubber material is smaller than a specific electrical carrying region resistance of the carrying region rubber material. The steps according to the invention are: determining an electrical guide strip resistance (W28) of the guide strip (28) between the outer side (22) and the inner side (24) and outputting a warning signal when the electrical resistance (W) exceeds a specified maximum resistance (W28,max).
