Largest possible tyre size and reccomended rim size

Can anyone help a new guy out here? I was hoping for some that don't rub on the inside, like some people don't mind this BUT... anyways. Basically i'm just looking for a simple answer to this burning question, and yes i've searched around a little bit, i guess i'm not as good as im sure somebody will answer this question with a link right away!

 

You want absolutely no rubbing? Stick with the stock size.

 

are you serious? You really can't go any larger? hmm... damn.

 

Well, there is a guy running 37s with no lift and he don't rub, but to take in all the work required to do that is pretty intense. If you don't want to rub at all, stick with the stock size. Even going up 1 size, you will lose the flaps. Mind you, no truck is the same, it's possible you could go up 1 size and not rub but unlikely. I'm sure you will get "I went to 265/xx/xx and I don't rub" every now and then but if you don't want to take the chance you should stick with the size you know won't rub.
