Hello people, have raised the summer tires and found that they are brittle on the side wall and have some small cracks in the rubber. The tires are DOT 0707 or 0908, i.e. just 4 or 5 years old, profile good 5mm. The Michelin Premacy HP were also always nicely dry and dark stored in the basement on a rim tree. Are I here about poor quality of Michelin? So far I always had good experience with the manufacturer. Will go to the TÜV tomorrow and ask if the things have to go down. A new set of tires in the kitchen size 205/50 R17 costs good 600€ Did you have a similar case? Greeting, Nightflight
