Question Trying to figure out offset to purchase same size spare rim. HELP

So I have some KMC XD 20 x 8.5. I bought these used awhile ago off a kid. He didn't know what the offset was.

So the choices are +10, +35, +50.

From what I have read I am assuming I have to get under the truck (not a problem) and measure the mm spacing between the mounting plate and the rim/wheel. Are my assumptions correct?

I was looking for easier options like if it would be labeled on the actual wheel. Anyone's two cents would be appreciated. Gotta go buy a tape measure and figure this ish out.

Look on the back side of the wheel, some wheels have it written/stamped on there. Good luck

I think factory is +35 offset..., I recently put a new set of wheels and tires on my truck.... I went with +18 offset.... I think it is a perfect setup....

Yep...you might have to actually take one wheel off the truck and look on the rim but it should be on there somewhere.
