Hello, my winter car I got new Goodyear Ultra Grip Performance winter tires. They were mounted by my tyre dealer in the evening. In size 215/45/17 also not quite cheap. When I looked at the tires in daylight the next day, I noticed that they are covered all around (running area and flank) with about 1 cm long nipples. My dealer said that these were residue from the production, which would normally be removed. The company Goodyear addressed this question. thought it was technologically conditional and at least no shortage…. On the tread the nipples are probably running off, probably not on the flanks. Only the scissors remain…. I see something like this for the first time after 25 years of winter tires. Did I miss something or are Goodyear tires basically so badly processed?
