Thanks for the help. I read through the thread, I still think mine is wheel/tire related as the vibration is noticed really only in the steering wheel. Car see's regular summer use and only sits for the winter.

Tires where new along with the wheels when they went on but I will check the wheels for run out this winter. If it looks ok I'll see about getting them rebalanced as well.

I might also be looking for an excuse to change the wheels again too.
