It happens in the morning only, weird. The car vibrates like a tire or something in the chassis only in the morning when I am going to work. I have no idea what it is but the only thing I can think of is the soft tires have a flat spot from sitting all night and once its been driven its fine.

any ideas?

Yea, that should be what it is. Mine does the same thing and it isn't that bad this time if year but in the winter it is pretty bad for the first mile or two then it goes away.

 

I can say from experience that it seems common with inexpensive tires. They don't have a good temperature range of operation basically. I had Kumho's that did the same thing. I'd recommend Sumitomo HTRZ3's or Firestone Wide Ovals. You may want to have them road forced and balanced. Roadforcing will show how your tire performs under the pressure of roadforce being applied to the wheel. (In case you hadn't heard of it)

 

275/40/17 Firestone Firehawk SZ50's here, a VERY good tire for our car, but I have the same issues...ESPECIALLY on cold mornings as well.
