That’s me for my use. You can put a 265 on a 9” wheel it will be fine.
You get what ever wheel you like and what ever offset you want. If you want the one that’s 17x9” -12 get it. The extra width of the wheel will make the 265/70/17 not as tall and the -12 offset will push the tire out more. It’s all what you want. The look you want. I don’t see a lot of folks running less then -12 offset without more modifications. I know some are running up to -24 and I’ve seen one put -44 on but not without modifications.
You won’t be able to fit a larger tire than 265/70/17 without a lift and some mods.
If you want to be safe get the same specs as OEM.
