Wheel and tire options on an '05 Z71?

[88lance]

Found an '05 Z71 I'm about to go check out. Stock suspension and wheels.
If I get this, I would really like to level it and put some bigger tires. Unfortunately I don't know much about the Chevy SUV wheels.
I will attach a photo below of what the specific wheel looks like.

Are these 7.5" wide usually? Curious what I can fit on it after leveling. If they are 7.5, I could probably get away with an 11.5 tire, unless those start rubbing suspension parts or something on these? If these are 9's I might could do a 12.50, depending on the rubbing issue again.
I've read 33s fit pretty well without rubbing on height.
Just not sure what size these wheels are, and what kind of width you can even run on these Tahoes.

Would be great to hear from someone with some experience on it.
Thanks! Pic of wheel below.

Stock wheels on those are 17x7.5". Not sure of the offset, but you can look at the back of the wheel and it's molded into the metal.

EDIT: not your wheel but it would look something like this (31 is the offset on the wheel in the pic):

So they made this same wheel design with different widths then? Not all 7.5?
With a 7.5 I could probably run the 11.5 wide as long as nothing else rubs. If they also made this wheel in 9's or 8's that would be great

No, what I posted was from the OE wheels on my '04, different wheel style. Just an example of what you might see on the one you're looking at.
