We are going to figure out once I know my delivery date, but I'm planning on paying for the tires. They did say they would have it ready to go though with 33's when I arrive to pick it up (whenever that may be! lol).
My dealer told me they would throw 33s on it for me no problem. You just have to match the width of the rim but no lift required. There is another thread on this somewhere but I can's find it right now.
