The car was at the dealer for something else and I mentioned this issue to them. They claim that the tires have "choppy" wear on the sides and this is what is causing the noise. I asked the tire installer to look for this when they put them on this season and they didn't say anything. I guess I'll see when I pick it up. The tire issues on this car are driving me nuts. Assuming this is the issue, is it even possible to have an e90 that doesn't cause uneven tire wear on the front?
