I had my oil changed and tires rotated tonight. Now my car is making this sound when going over 60. It is fine driving around town. What is causing that sound?

 

If it has been a long time since a tire rotation your tires will ware in a funny patter. The front side of the tire tread that hits the road first will wear more than the lat side that hits it. Sometimes this may cause a road noise at higher speeds. It should go away over time it this is the issue. A decent habit is to rotoate tires round 5,000 miles. My advice may be incorrect feel free to correct me if I’m wrong.
