I have a 2000 Dodge Stratus with 14 inch tires on it. The car has been making a rumbling noise coming from the rear of the car. I thought maybe it was the tires I had on the back of the car as they are a different tire than the front. I rotated the tires yesterday and still have the same noise and it's actually very annoying. It just sounds like a very aggressive tire making a rumbling noise as you drive on pavement, but it's not. Can anyone give me some suggestions as this is my daughter's car and along with it being an annoying noise I just want to make sure there's nothing wrong with her car.
