We had contis on the 2000 323i and they were the noisiest tires. As they neared the end of life they got to the point where you didn't want to drive the car it was so loud. We put similar Bridgestones on the 323i and drove them 50,xxx miles before selling the car. They were as quiet from day one till the day we sold it.
