2004 9-3t with 45,000

Current tires are Bridgestone G009 now with 15k on them.

There is more road noise than I would like. Worse on smooth asphalt at 40ish mph. Not too bad on the highway. Not noticeably worse with turning.

The tires look ok to me.

How can I tell tire noise from bearing noise?

Wheel bearing noise sounds like a rough growl or grating sound that will continue when the vehicle is coasting and the transmission is in Neutral. Since wheel bearings are not pre-loaded, a wheel bearing noise should diminish considerably if you lift the wheels off the ground.
Tire noise sounds like ... tire noise.;)
