a 17x7 with a 50 offset tucks further in than a 17x7 with a 30 offset. 20mm to be exact.

That makes absolutely no sense. You are saying they measure positive offset backwards.

You just contradicted yourself. Which is it.

From the other comments you made, and the pic that is identical to the one I was using, you are agreeing with me, but I guess you just can't admit that.
