Generally speaking, a 265 will be fine on a 7"-8.5" wide rim. Usually a tire manufacturer will list a suggested rim width. That said, where are you finding a 265/75-17 tire? The Yokohama site doesn't list that size for a 17" rim. I had 265/70-17 KOs on 8.5x17 Stealth 6s. That said ... again, LOL! I had a slight rub at full lock right in reverse.
