I am lifting my 2005 sport 3" in suspension and 1 1/2 body. The 17" x 9" wheels that i am interested in have a -12mm offset. I believe stock is +30. I plan on running 285/70/17 {32.5"} tires. This calculates out to the wheel sticking out 2 3/8" further from the stock position. I really did not want them to hang out that far from the body but i read a thread recently that sid that the 285's will rub with the stock wheel because it is not offset much. Any insight?

 

I replied to your PM. I forgot the offset to backspacing conversion, but it seems that 2 3/8's inches further out is quite a bit. You might have problems with your tires hitting your fender. Let someone else chime in before you take my word for it.

 

Here is the relationship between back spacing and offset:
