I had the worst roaring noise on my 325i. No one at BMW could or would want to solve my problem. Only Carolina Tire test drove it thoroughly and came to the conclusion that it was my run flat tires. They made the recommendation to put on a set of Continental Extreme DWS tires, gave me free road side assistance nationwide and guess what? No more road noise, my BMW is riding like what I always thought it would. Thanks to Carolina Tire for saving my BMW.
