Look at TireRack.com. They use 3-Series sedans to test tires on their test track, so results should translate directly to us.
I have new Bridgestone run flats on my 2011 328i that I bought as a certified car in February. Road noise is excruciating on our poorly repaired roads here. The noise resonates all through the front end into the car.
Next replacement time, if not sooner, I will very seriously investigate non run-flats. I understand they fit OK on the stock rims.
