you are ****ing LOST.
STOP ASKING QUESTIONS AND JUST STICK TO THE 17x9 +42. Anything wider than a 245 will require a ROLL. anything wider than a 255 WILL REQUIRE A PULL. hell, even that fitment can cause too much problems for someone as lost as you. And if you only plan to run a 245, i'd stick to an 8" wheel. you obviously have no need for wider wheels.
