Hi!

Is the noise coming from the tires or somewhere else?

I just bought a X1 Xdrive23d and have 225/45/18 Potenza RE050A non-runflat tires all round. I also got Eibach -30mm lowering spring kit installed.

When I first entered the highway I noticed a whirring/whistling sound coming from the front end both sides. it was really hard to tell where it came from.

I found out it was the air conditioning/the manually adjustable air flow vents that made the noise, in other words, when I tried different positions from min to max in air flow into the cabin, the noise went away occasionally.

Now when I drive the car I haven't noticed the noise anymore. Strange thing but I am happy at least now!
