What makes a pulsating noise in a car?
I have a pulsating noise that sounds like tire noise but its difficult to tell whats making it. I get the noise when cruising around 40-55 mph, if I go any faster it dissipates. If I could compare it to anything its like the noise wind makes when you have a rear window down and the pressure difference makes that pulsing sound.
What makes the womming noise when you go over 80km / H?

Why does my Car Make Noise at 45 mph?
Since it only happens at 45+ MPH, and is fairly quiet to begin with, listening from outside the car is not an option and it gets drowned out by the wind when the windows are down. The sound only seems to be slightly affected by vehicle speed.
When does the noise change independent of engine speed?
Note that the question specifically states the noise is independent of engine speed – as long as the vehicle speed is above a certain point, the sound remains present and its pitch and volume are not affected when the engine speed changes independent of vehicle speed (e.g.: down-shifting while maintaining 60 MPH). – Iszi Oct 23 ’15 at 14:53
