Guess it's a good excuse to change out some bushings. Now will the rear cupped tires even out being on the rear? Or are these tires just fubar'd.

Did you ever find out what the problem was? I'm having literally the same exact problem.

Cupping can definitely cause this issue. I had my car aligned in the early Spring when I switched back to my summer tires. However, my tires still got cupped because my alignment was again thrown off from the post winter apocalypse roads here in Indiana and the city being so slow to fill potholes. The alignment issue seemed mild and by the time I got the alignment corrected the damage was done. I have had balance, alignment, and bushings checked and everything is good. However, I get plenty of vibration at interstate speeds, especially after going through a large sweeper and heating up one of the shoulders. I could have the tires shaved to correct but I am past half life so will just live with it. It can be very annoying at times but tends to smooth out somewhat as the temp across the tires changes.

Yea the front tires had cupped.

I rotated them to the rear and vibration went away about 98.9%.

Who does shaving? I should have more than 50% left in mine.

TireRack shaves new tires for a small fee.

Sometimes random tire shops have tire shavers.

Default Steering wheel vibration highway

A update on my vibration...

I rotated the tires front to rear and the vibration is completely gone. So as Rymaggi mentioned, cupped tires can cause massive vibration which can come and go on the fronts, but be completely imperceptible on the rear of the car.
