Lexus IS 300 tires.?

I bought a certifies IS300 recently and the steeiring wheel wobbles in the morning for some minutes while driving because the tires are cold. The dealer says it's because they're high performance tires so they "flat spot" till warmed up. I think this is a bunch of crap because I have had high performance tires on my Vette and they're fine? What else could it be?

Over night the tires will flat spot enough to make the wheel wobble for a coupple minutes but it is no problem. Vetts are totally different. The tires are wider and lower profile on most and not comprable to an IS 300. I love both cars although and could be happy to take either off your hands..
