What's the largest tire I can put on a 15X7 rim, will a 235/75/15 work?

Long ago I had a set of 265/75/15 tires on my truck and its stock wheels.
I am sure a 235 would be fine.

But I am no professional.

You can put just about any size tire on a 15 in rim. Biggest I've seen in person were 40 inch tires.
I personally run 31x10.50R15s and 33x12.50R15s on my squares with 15x7s. 235/75s are equivalent to a 29in I think, pretty small..
All depends on what your truck can support. What type of square do you have? I know on a stock C10, the biggest you can go is 31x10.50, but stock 4x4s, 3/4, and 1 tons you can go a bit bigger.

235/75-15 is no problem on a 7" wide wheel. 31x10.5's will fit without issue as well.

I have 7" wides on my GMT400 and am running 31x10.5 and they look great. Could go a little wider, but they the sidewalls will get a little iffy to me. Haha.

a lot of shops won't put anything much wider than 10.5 or 11in on a 7in wide rim. I run 33x10.5xr15 on 15x7 OEM aluminum wheels. that's about as big as you can go. I think rally wheels are 15x8in and can accommodate 12.5in wide tires.

31x10.50x15 came on mine. I just checked this morning to see if I could size a 20 before buying a lowering components.

Only if you go to shops that have silly things like insurance, and phone numbers. If you tire guy is named Phil and his "shop" is a metal shed from Home Depot.....he is usually cool with trying the wide boys.

The rallies I bought are 7" wide. I do have two 8" wide rallies, looking for two more.

235 75 R 15 was the standard size for most of the C10s and K10s if I recall.
I have had 33s on 15x8s down to the 235s on 15x7s with no issue.
