Default New Goodyear Billboard Out-of-Round

I just got a set of Goodyear billboards (aka Sport Car Special aka Cobra tires) and have a problem with one of them. The tires were balanced on a Hunter GSP 9700 Road Force machine and three of them came out very nicely. One, however, had a road force of 88 pounds (lower is better, with less than 20 desirable) and the tech told me (and showed me) that it had a pretty obvious flat spot. This was after he matched low spot on the tire to high spot on the rim, etc. I know from other posts here that these tires are prone to flat-spotting after setting up a while on the car, and that this self-corrects after a few miles of driving. I haven't put these tires on the car yet but I'm wondering if I should go ahead and drive it a bit and see if the flat spot goes away. Anyone else have a similar experience? Suggestions?
Thanks in advance.
