Help ! I have a 2004 Stratus 4 door SXT coupe. When I'm on the highway, there's a nasty noise which seems to come from the tires. Kind of like a high pitched, warbly sound. I operated the wipers during the noise, thinking that it may be the cause, but no luck. It doesn't seem to change much over concrete or ashpalt. Could the "mag" wheels cause this whistling ? Would like to hear from anyone who may have experienced this. thanks.
