05 Jimmy lift and wheel swap
I’m looking at swapping my 235/75/15 tires for 265/75/16 or 17’s. I just purchased a 2.5” RC lift, and would like to pick up some used rims, hopefully from a junkyard. Are there any junkers out there with 16” rims and a 5x120.7 bolt pattern?

Not a lot of factory rims out there with the same bolt pattern. S-series trucks, and GM family RWD cars like the Camaro up to 2002ish. The thing you have to be careful with is the backspacing on the rims. Too small backspace, and the rims will stick way out and make it hard to turn without rubbing. Too much backspacing and they tuck way in, also making it hard to turn without rubbing.
On a factory 4x4 rim with that lift you should be able to fit up to a 31" overall height tire without any other modifications necessary. Once you change the geometry of your rim setup, then the tire height that is possible without rubbing while turning will change too. If you're willing to do other mods such as fender trimming then you have a few options.
The Blazer & S10 Xtreme had an optional 16" rim, with 4.5" backspacing. Lots of people have used those, but they can be hard to find. Most Camaros and Firebirds also came with the correct bolt pattern and 4.5" backspacing up to about '95. After that they switched designs and moved to 6.8" of backspacing which can be challenging to use without needing spacers.
In the winter I run '98 Camaro 16x8" rims with 245/70/16 winter tires, and in the summer I run Camaro SS 17x9" rims with 265/70/17 BFG AT tires. Both of these rims have 6.8" backspacing, and I have a ZR2 rear axle (3" wider than the factory axle) as well as 1.5" hubcentric spacers on the front in order to get the proper track width and clearance.
On a 4x4 Blazer depending on what tire size you choose you may run into issues with the front tires rubbing while turning, especially on the rear of the front fender well. It's pretty common to trim a bit in this area to help fit when changing rims and tires.
Out of curiosity, what part of Canada are you in?

The height of the rim isn't really what matters. It's the backspace or offset (depending on which way you're measuring), and the overall tire height.
You should be able to put a 31x10.5x15 on factory 4x4 rims. I think this is the recommended setup with the RC 2.5" lift? These tires are quite a bit beefier than the factory 235's.
If you want the track width to be wider, then a lower back-space rim (ex. 4.5") will make things wider, but you might have to massage or trim the rear of the front fender well to prevent rubbing when turning and hitting a bump.
