"Humming" noise at 47-50 mph

Ok heres the situation, I cant figure this out, but I am going to take off the wheels and see whats going on but figured I would see what you guys think.

2003 grand am 3.4, 54,xxx miles on it, etc etc. When I am going about 47-50 mph, the front end “hums” a little bit. It does not hum under brakeing at that speed. Im thinking it must be one of the following:

**Bearing starting to go because its not doing it at all speeds, all the time, just seems to be at said mph.
**Wheel/rim noise. I have my stock winter rims on it so I wonder if its just some rim noise vibration.
**The last thing it might be, is one of the calipers/ or slide pins sticking.

What do you guys think?

considering it’s a G/A it’s a wheel bearing.

thats what I am thinking, i will find out once I take the front end apart, I replaced both the bearings about 30k miles ago when the speed sensor went bad in both of them.

I’m with these fools. ^^
