Vibration at high speeds

02 Bonnie. Vibration at high speed. Anyone have an idea?. All wheel bearings are ok. Replacing all tires tonight. Thinking that a bald spot might be the problem. Any insight would be much appreciated.

Welcome AF, in the steering wheel, front end, in the body, what is the history, not enough info here to really help.

Yeah, sorry about not providing much information to go off on. I was getting vibration in the rear right but it was traveling through to the steering wheel. I put two brand new sport tires on and had two touring tires on the car. Replaced the two tour tires tonight and I no longer have the vibration. Must have been a either a bad combo of tires to have on the car or a bald sport on one of the rear tires.
