If you do have to trim, it will be the rear quarter panel/wheel well area at the bottom of the quarter panel behind the rear wheel and is this sentence running on and on enough for you? I suggest making a template before so both sides match There is an article in the tech section of Dweeb. I will look to see if I have a pic of it in the Show it Off section here. I am having a hard time downloading images onto LRO so I have to rely on pics that I have already downloaded.
Nope, looked, don't have any of the rear area to be trimmed but check out that Dweeb tech article.
I am running 265/75/16 MT's on mine. Go to the Show it Off section and see the pics of The Black Widow on the Peligreen Trail and on the Blue Lakes Trail. I don't think you can see the trimming but it will give you an idea of how that size tire looks.
