Will window deflector take care of that problem? I am curious.
My SUV is loud as hexx!

Thank you all for your responses. Now I know I'm not nuts and can quote
scientific terms to explain the issue. Of course I'm still stuck with the
vibration problem at 1500 rpm. Thought is was the right rear tire, and it
may still be, however the exhaust system now has me on a different path.
Then again maybe I should just turn up the radio and get over it.

John,
It's not a problem if the AC is used. I rarely see anyone with the windows
down or the sunroof open--regardless of the outside temp. The closed
windows mean that we solve the "loud sound" problem and we also keep out
the pollution such as the odor of diesel fumes.

Oh, yeah, I know that one. That's what happens when you don't shave your
Karmann Ghia often enough...

Not uncommon to be able to produce this effect with certain speeds and
window configurations. Try cracking a front window a bit.

I hang around cyclists in hopes of some pretty young lady thinking it is
"Goretex shedding" but so far no luck.

Hey, Accord Ex sunroof does the same thing.

I've meant to try putting some deflectors or vortex shedders or
dilithium crystals or eolian transmogrifiers on the leading edge to
prevent it, but so far haven't actually bothered.

Beryllium spheres or unobtainium plasma rectifiers might do the job - check
the wrecking yards.
