sometimes this happens to me when I get a rock stuck in my tire tread.
or maybe you have a bolt or a nail or some other piece of debris stuck in there.
it may be making the noise all the time, it's just that when you reach a certain speed, other noises that the car makes may drown it out for example road/tire noise, or engine noise.
does it seem to have the same beats per minute as the tires have revolutions per minute?
I hope its that simple
can you feel it as well as hear it?
if not, then I think its debris
if you can feel it then it may be something else
