Steering wheel shaking like crazy? Options

[mkernz22]

Alright, so pretty much when ever I am driving, the steering wheel shakes like crazy.
Even with two hands on the wheel trying to control it, there is so much vibration.
I know my tires are getting pretty low, but they can last a couple more months.
I'm not sure if anyone else has had this problem, but do you think it's the wheel bearings, unbalanced tires/rims, or just low treads?
The car pulls to the right when I let go of the steering wheel too.

Please help me out!

I don't have any bent wheels, I checked that right off the bat. The tires are worn a lot near the out edge of the treads, but the middle seems to be decent.
When I'm doing about 40mph on the road, the feedback isn't too bad cause I don't notice it half the time, but when I'm on the highway doing about 80-85mph, the feedback is unbearable and it shakes like f***ing crazy! When I replaced the brake pads not to long ago, both front sides had uneven wear. The driver's side had more wear on the inside pad than outside, and the passenger side had more wear on the outside than inside pad. Bad wheel bearings possibly?
