When changing to the summer tires, I found that my winter tires at the “outer tunnels” were partly driven off. is affected by this every 4-5 tunnels. Otherwise the tires still have 7-7.5 mm profile depth. However, the tires are already 6 years old and there are new ones for next winter. If the wheels would like to sell, of course with the reference to the damage my question, you consider the damage to be highly safety-relevant, or you could still use them. I’m gonna put some pictures in here.
