My tires are brand new PILOT AS4s and the tire set up is 245/35/20 with 8.5 in rims in the front and 275/30/20 with a 9.5 in rim in the back, what is causing the vibration?

I'm assuming aftermarket wheels since you have hub-centric rings. Even though you have the "correct" size, I would still suspect the rings. I've had nothing but trouble with aftermarket wheels & centering rings.
