One disappointment in the new MX is the amount of road noise at highway speed. Is have the 22" wheels so I understand that people say they are louder. However, I had big low profile tires on my BMW X5. This car has a lot more road noise. Has anyone noticed this same issue? Is there a way to mitigate it after market? It seems to me that many years ago I heard of spraying the wheel wells with foam or something. Any suggestions would be appreciated.
