I have an 03 4.6is and yes I run the stock staggered wheels. I also have an 03 4.4 that my wife drives. In the winter I run a designated snow tire on the 4.4 and use her all terrains on the 4.6. It just looks a little goofy. What you say about offsetting the rears makes sense. I will use these run flats on the 4.6 in the winter, occasionally I will have it in snow but not often or for very long.

Thanks for your input but I only experienced the vibration when I installed the E-70 wheels on the 4.4. It has to be the difference in size as QSilver said so when I install the hub centric rings on the wheels this winter I will let you all know.
