Ok so its 27 degrees here, coldest it has been since I got my car in late Sept. Usually on a normal day I feel vibration at 1500rpm and 40-50mph, but goes away after 10+ min of driving, and it really isnt that bad but I do not like it.

Well just now at 27 degrees, 1500rpm, 45mph, it felt like my tires were square, the vibration was horrible, so I assume this vibration is 100% flat spotting now, atleast in my cars case. I have an appt. on Friday at Acura for them to fix the car pulling to the left problem that many of us have, as well as rear deck rattle and I will mention these horribble tires and see what they say.

I bought my car in June and didn't see what all the fuss was about with flat-spotting.

It wasn't until nighttime temperatures dropped below around 65 degrees that I started to notice the problem. It's annoying, but not enough to convince me to replace the tires. The problem goes away after around ten minutes as you've noticed.
