I haven't had those problems at all with any of my Contis or any problems really. Different things happen to different people for different reasons. I can only speak from my experiences with Conti's and those of my shop-mates since I know them and the general riding they do.
The final straw was the wheel strike above. I've used lots and lots of tires over 30+ years of riding and have never had the problems with any brand like I have with Continentals. They are supposed to be a high quality tire with a premium price to match. In my experience, they are just have the price.
