I am running 35/12.50/17 Toyo open country M/t's which are very similar tires. I have -12 offset and bilstien adjustable struts in the front put at 2". I only required very minor trimming at the bottom of the wheel well plastic. Brandonjansen seems like he has the right answer for you.. 17" rim and 18" rim may require different offsets.
