If I'm not mistaken, a 265/75/15 is roughly identical to a 31x10.5 tires.
You can fit that stock. Newer Rangers can come from the factory with that tire, and a guy at my work has one that he put 31x10.5's on with stock wheels, and he has absolutely no problems.
They aren't TOO much bigger than your stock tires, in other words, the truck would not look that much different. Unless you want to put the lift on it, but then you may start running into the "tires are way to small" look.
But sorry, I do not have any pictures.
