Lifts and wheels

[Emoris]

I recently purchased a 98 1500 that I believe has about a 3" leveling kit on it. Unsure as the person I bought it from never bothered to ask who he bought it from.
Almost seems like the shocks werent changed when they lifted it so I'm thinking I'm going to buy a whole kit and redo it at 3" and this time with aal rather than blocks since the blocks they have installed appear to have stress cracks running through them.
Anyways im really just wondering what size tires works well at that height since they had a set of 315/75/16s on it and they have to be ordered around where I am and they rub when turning
I'm trying to find something that's easier to find that will fit nicely under it

285/75/16 fit well.

The tires are likely rubbing because I'm assuming it's on stock wheels? Aftermarket wheels with more offset you can get away with no rubbing using the same tire size
