Trying to figure out my current offset

I'm currently using a set of OEM 3rd gen off-road 16" wheels combined with 1.25" hub centric spacers to give a slight poke.

Would anyone happen to know what the approximate offset of this setup is so that I can browse wheel options that would allow me to eliminate the spacers?

Additionally would anyone happen to know the width of this wheel type?

 

After some searching, it looks like the wheel is probably 16x7 with a +25mm offset, so if I'm processing things right , the offset with a 1.25" spacer would be close to -7mm, so just shy of -10

 

Your math is looking good, you’ll have a bit of tire poke
