With my girlfriend’s Mini Cooper (Beziner BJ2003) an extremely loud running noise makes itself noticeable which increases in intensity with increasing speed. It is comparable to if you had bad tires on it that are extremely loud or have something unbalanced. The loudness is usually quite violent, I think that’s how it sounds when you drive over the highway with a tank (from inside ) with 100. Strangely enough, the car drives completely normal and outside hears m When we bought the car the noise was already there, the previous owner said it was because he changed the winter tyres from the rear to the front and because it sounded like a tire running noise we didn’t really worry about it. Since now the noise is still present in the summer icing I was a bit skept What else could that be? Wheel bearings worn? Track rod heads?
