Hello! New to the forums but long-time mustang owner looking to build some advice and leads for when I'm back in town next week.
I have a 2005 GT which just had a gear rebuild and new wheels installed. New sizes are 18x9/18x10, with new Nitto tires on them. The problem (a high pitch whine) started after this wheel install, and so they're the natural suspects, but I unfortunately don't have the old wheels to put back on and test. Conditions are as follows:

I have a 2005 GT which just had a gear rebuild and new wheels installed. New sizes are 18x9/18x10, with new Nitto tires on them. The problem (a high pitch whine) started after this wheel install, and so they're the natural suspects, but I unfortunately don't have the old wheels to put back on and test. Conditions are as follows:
- Whine starts light at around 65-70mph, rising in volume to very loud at 80-85mph.
- Whine is dependent on speed alone; putting in the clutch or accelerating/braking don't make the sound go away (unless you decelerate below 65).
- Car has 100k miles, so decently worn, and I've only had it for the last 10% of that.
- Front left wheel bearings had to be replaced a few thousand miles ago, so that's on my mind, but I can't seem to get the whine to change by swerving at high speed. Rear wheel bearings, perhaps?
- Gear rebuild was a couple weeks of ago, but since the noise is not related to acceleration or gearing, I don't think it's an issue.
- Rear rotors are old and could use replacement soon. Could rusted surface on the rotor cause some vibration/whine on the wheel? The high-speed-only aspect makes me unsure of a lot of behavior here, so mind my speculation.
- Tires? Nitto Invo's, but they're brand new, so it's not a wear issue. Maybe lowering the pressure might help?
- Have no idea about axle wear.
