Flat spots on tires?

So I've noticed that if my car sits for a day or two, the first 10 mins of my ride feel like the tires had developed flat spots...
Very strange as they are still fairly new OEM tires. I've even double checked the PSI and I'm at 37/38 all around. I mentioned something to my local Lexus service dept and they claim I should do a road-force balance. My initial thought is that I don't need that since the car drives smooth after the tires warm up.
Anyone else have any experiences like such?

"The tread compounds and firm, nylon reinforced internal constructions used on high performance and high speed rated tires are more susceptible to flatspotting.
Heavy loads and too little air pressure in the tires (underinflation) will allow them to deflect more where they come into contact with the ground. This allows even more deflection, increasing the severity of the flatspotting.
Cold ambient temperatures make rubber compounds stiffer, increasing their tendency to flatspot."
