If you don't think any of these could possibly be the reason why you would have this vibration you may want to have the vehicle checked just to make sure. I hope that helps to possibly answer your question on why this happens to you.

1) I have experience with both my all-season and snow tires.
2) Active fuel management is on the SS V8 Automatic. (this is on V6)
3) And he stated car is all stock.
Unless it is excessive, I think it is just the design of the car.
