Wheels were Whistiling while i was doing 60-70MPH???

I was on the NJTPKE this past Saturday and something happened that i never had happen to me before

My X's wheels started whistling?? like if air was getting in the wheels wells and just whistled away??

Anyone know what this is??

I had no vibrational issues or anything else wrong -it was just whistling loud (over my radio loud!!!)


any comments ?? (appreciated)
