The sound starts around 20 mph and is pretty constant all the way up to 80 mph. It's really annoying and the dealer shop hasn't been able to locate the source of the noise yet. Does anyone have a suggestion where to look or what could make this sound?
The noise tend to get a little better on new and fresh asfalt which could indicate tires. But this was already ruled out with a different set of tires. Actually we have tried with two different sets of summer tires and one set of winter tires. Makes no difference what so ever.
Any suggestion is really appreciated.
Thanks!

My 330xi has loud tire noise on certain types of concrete. The tires sound normal on asphalt and new concrete but extremely loud an old concrete.
