Well, now I'm thinking that the vibration is definitely from tires. When I had the tire off I rolled it on the ground and it started to lean left to right. Then I felt the surface of the tire with my hand and it was very bumpy. I think the tire should be kind of flat. Even know there is still thread on the tire, I guess the time took it part and messed the surface of the tire up. I'm going to a junk yard today, they got tires @ $10 a pop, see if they got something worth putting on my car.

 

Definitely were the tires. Picked up a set of Continental ExtremeContact and man they ride awesome, already experienced some show, and for an all-season tire they perform well

Oh....the vibration is almost gone, turns out to be that my rim is bent a little bit past the point of balancing.
