okay, see if you have 2 little plastic flaps where the roof and glass meet, like in the lip, on either side, towards the front of the car and flip them up when your going to get that resonance, in city driving, about 60 to 80 kms

You were right about WHY it does that, its air pressure, same kind of thing on an airplane wing.

if you dont have the flaps or they dont work for some reason, crack a window more than a half inch and it will even pressure out

good luck
