Aggressive Wheel Fit (not stance) Question

I'm heavily considering getting some beadlocks. The wheels I'm looking at are a 17x8.5 with a -15 offset and backspace of 4.16. Tires will be 265/70R17. I have factory 20s now, so it's difficult to measure out. Could anyone with some 0 offset Methods please measure out tire clearances at full lock on each side? Do you think they will clear the stock fenders at full bump? I don't want to cave in fenders... Although that would give me an excuse to go glass.

 

Stock height? I don’t think you will clear.

 

Stock height for now. There's plans that need more time and money.

 

@KevinK I know you have/had some crazy ass wheel specs. You got any input for me?

 

UPDATE: I had left a message with a friend of mine that owns a small tire shop and with his help and some online calculators, it's going to be too much for something that gets driven on the street. His words were "Get something that fits right. I don't care how much they cost, this is a terrible idea for a street driven truck."

 

Sorry, I just saw this. Did we have this conversation on Facebook? It sounds familiar but was a while ago. LoL
And I suck at names - let alone when people have a forum name, an IG name, a Facebook name that may or may not be real, and who know what else.

 

We did.
