Remarkable high rolling noise for new Audi A4 Avant

I already have a thread over there with the Audians, but maybe there are more tire experts here. After about 2,800 km with my new A4 B8 Avant 1.8 TFSI I am quite shocked about one thing: the high rolling noise! Every smallest change in the road is clearly “passed through”. Since I still have my 16-year-old A4 B5, I also have the direct comparison: almost a tram opposite the old additions come from 180 km/h for my feeling also very deutl of course, it is clear to me that with such an excellent quiet running engine and a well-muffled interior, other noises are all the more noticeable – and possibly can disturb. I am currently driving quite normal standard wheels 16 inches with 225 Conti Premium Contakt 2. Is there anything known about this? Actually, the tyres are not noticed in all tests by particularly loud rolling off. What interests me: what are currently recommended tyres in this dime nsion regarding low rolling noises? On good luck I don’t want to tear down the almost new tires immediately, but if certain “lesser” alternatives open up, I will seriously think about it, because the sounds dampen the joy of the new car already very much
