Look on the first thread up at the top of the forum. There are many good references in that thread. I left three links with good visuals on the wheel clearence on page 3. I have a 3" UPYOURKIA lift, but that dosen't make a big difference. I'm sure you won't have to make any trimming to the bumpers at that size tire. But it will look alot better than it did.
