			Hi rob,As Charlie stated, the initial vibration quickly dissipates; all three of my tire varieties have done it, but the most noticeable were the original Contis.  I don't know if it was something peculiar to the compound or the effects of "age" but they certainly were bouncy for a few miles particularly after sitting idle for a few cold nights.  You may recall that I am running 18s, so the effect may be more apparent than on 17s.
 
 Interestingly enough, I bought a set of the "ridiculously priced" Tire Cradles shortly after I got the car, in my naivete, to avoid flatspotting; maybe they work as proposed since the vibration is so transient -- more likely, as Charlie alluded to, current technology makes permanent flatspotting from short-term storage a non-issue.  I still have the cradles on my garage floor, but they serve more as car positioning markers than anything else.
