15x8 and 33x12.5s

[67ss&99ss]

I've got a question. I am working on a 1972 K/5 that has not been lifted. I have been doing some research prior posting this thread, and it seems in the offroad community, the combination of a 15x8 wheel and 33x12.5 tire works well both off road and on the road. I wanted to see if any of you were running this combination on your blazers and if so, do you have any fitment issues? The wheel I was looking at has a 4" backspacing. I will mostly drive this on road, but I will venture out on some mild trails from time to time as well.
