Tire noise at this point is my largest reservation. For us, the whole point of this vehicle is comfortable long trips (we frequently do 300 miles on the weekend to our camp).
My friend has the RWD with Aero's and I did not find cabin noise to be an issue. But I was distracted a bit by all the other aspects of the car. I have since test drove a P3D+ and the tire noise was borderline ridiculously bad. I have assumed for now it was the 20" wheels at who knows what pressure. This was not the same road, and as some folks mentions the texture in the road can make a huge difference. So the road could have been a bit of an outlier for road noise. my dB meter was reading 88dB, I assumed it was broken, it might not have been it was pretty bad.
I plan to measure my friends RWD probably tomorrow night and compare it to my Jeep Summit (which I absolutely love for a quiet ride) and my wifes VW CC which has always been pretty bad road noise. The Jeep has double insulated glass on front and sides, Active Noise Cancelation, good insulation, just a V6 and nice tires (I forget what they even are). I don't expect the M3 to beat Jeep Summit but I'd like to get reasonably close. I don't mind giving up a little range via tire pressure or different tires if it solves the issue.
The 20" wheels surprisingly handled bumps fantastic. That was my other concern.
I have a P3D with Aero's on order.
I wonder if the glass roof plays a significant role. I know when I close the Jeep Panoramic Roof it makes a fairly significant change in cabin noise. And it's really an extremely thin cloth that is between you can the glass.
