2005 impala roaring sound

what makes a roaring sound while driving? I have new tires and alignment,but it still roars,loudest at about 45mph,and less at about 60mph and above.

This Is One Of Those Problems That Are Hard To Cyber-Diagnose With Any Accuracy.

We can’t hear the roar and the car isn’t here. I would suggest that possibly any of the four wheel bearing/hub assemblies have worn out. That is just a guess. Can you or passengers determine where the noise is coming from? A bearing is located at each of the four wheels. Sometimes backseat passengers can tell.

You will probably have to take your favorite mechanic for a ride, let them hear it and venture a guess or two, then take it into the shop to check their suspicions.
