Manuel,
Based on my two Dunlop experiences: D60A2 on my E30 and 8080's on my wife's
E36, the unfortunate answer is yes. They are even nosier on concrete roads
with mid-frequency 'howling' noises.
If your tire source has a 30/60/whatever day money back guarantee, I would
humbly suggest exercising that option and going with better tires.

That might not have been a good test: if you can see the play in the wheel
bearings by hand the wheel is pretty close to falling off. Bad wheel
bearings start howling long before they start wobbling.

Does the noise increase during turns to one side? If so, suspect a wheel
bearing. 
If not, this may be a good time to drop by a trustworthy mechanic and let
him diagnose (and fix) the problem for you.
