77 K5 stock wheel size?

[77ck5]

Wondering actual stock wheel size for the 77 blazer? No access to it currently. Is it 15x8 , 15x7? Offset? Looking to get a new set of rims and tires prior to going back to calif. I know rims on it are 15" is alll and the tires are 31 x 10.5. Would I be better going with a 16" for tire availability ? I plan on leaving the ride stock height for now as well if that helps. Seen loads of info on tires just not wheels

15" will still have more choices for tires than 16"
Are you looking for choices of nicer aftermarket wheels?
I have some aluminum wheels I took off when a switched to 8 lug I would sell you cheap.
I have 2 different styles

I’m not after nothing fancy. The ones on it are all rusty and it needs tires badly. You could send a couple photos that would be nice
