I've got kind of a roaring sound from my 2009 R56. The tires that are on it have always been loud, and at first I thought it was just tire noise, but it seems to be getting worse, and now I think maybe it's a combination of tires and something else. It's loudest between about 40 and 70 miles per hour, and doesn't get much quieter if I shift into neutral at speed. I wanted to try shutting the engine off and coasting, but it's an automatic and won't let me.

No other mechanical noises, and no driveability issues other than the noise.

Ring bells for anyone?

Thanks

 

Check the run-out on your hubs/bearings. Once they wear out they can be very noisy. I would suspect the front ones since the rears would not be as noticeable.
