Do you konw if there was any of the flat stop gel in the tires? if someone had put that in there it would have all settled in the bottom and could cause the problem.
Nope no gel in the tires I bought the car new. From the points brought up in this post I'm inclined to store it with the tires on the ground from now on. One thing I thought of is if it was possible the steel cord in the tire is sort of stiff from not being flexed for months and creates the vibration. It hard to describe the vibration but it scares the sh*t out of ya. The vibration seems to be none directional.
