I know! Wheel off set help

I’m looking at purchasing some
fuel Anza wheels ANZA - D557
MATTE BLACK W/ ANTHRACITE RING
16x8 6X139.7 ET: +1 ...
I currently have on my truck the OEM 2019 off road wheels with the 1.25 spyder trax
The tech said that even though these are +1 off set they’d only be shy of where my current 265/75 tires poke out by 1/4”
I’ve searched on the forum here multiple times and I keep seeing that you’d need -10 to -12 off set to achieve the same 1-1/4” I have with my spacers ...
Anybody got done helpful knowledge about this before I thrown down the bucks ??

 

Your stock OR wheels are +25 which is about an inch. The tech is right on, with what he told you.

 

Awesome thank you

 

Your current wheel and spacer is equivalent to a 16x7 ET -6mm...
