2007 explorer humming noise from wheel---bearings replaced and new tires

Did you purchase a different brand tire than was previously on the vehicle? If they are all terrain tires they can be a little noisy. My F 150 quieted down quite a bit when the original all terrain tires were replaced with highway tires.

Same tires put on. It is now thought the rear bearings are the culprit. In the shop to evaluate right now.

Thought all the bearings were replaced. Must have changed only the front's since I believe the rear's have to be pressed on and off.
