If you just trying to run a 245 wide tire, why a 9" rim? A 245 wide tire belongs on an 8. As you can see, a 9 inch rim wants a wider tire to fit well. If a 245 tire up front is what you want to run, use an 8 with our tried and true backspace and a 245/40/18 and call it a day. I thin you could benefit from our guidance... Give us a call.
