So when I go to leave for work in the morning when it is cold the car acts like one tire has a lump on it and will rock slightly.

Once it warms-up though no problems at all. Any idea?

What's your definition of cold? Some tires aren't designed for extreme cold and the compound/rubber used in the tires forms to it's standing state, therefore will have a slight flat area when you leave it parked over night. When you drive it in the morning the tire has that one spot which will cause a bumpy ride, until the point that the friction of the road warms up the tire and gets rid of that flat area.

That make sense because my idea of cold is 0-10 degree F
