Wheels for a duster offset and backspace

Easiest way to determine the backspace is shown in the video I posted above, pull the wheels and measure from the outside of the lip on the wheel on the backside to the mounting surface. The rims may also be stamped or marked on the inside, but that will probably be an offset number.

The problem is that with an A-body the backspacing needed in the front and in the back isn’t the same. The wider the tire you’d like to use, the more that’s true. So, to use the same rims front and rear limits your width.

The other issue is the rear axles aren’t all the same width. A-body 8 3/4’s are wider than A-body 7.25 and 8.25 rear axles. So, what rear axle do you have?

I’m also assuming you have the 5x4.5” bolt pattern since you have 18’s already.

Ok, thank you. That makes sense on how to measure offset. I took some pics last year when I checked the brakes (attached) but I'll have to take them off at some point and measure to be sure. It's in storage now.
I like the idea of having the wheels/tires all the same but it's not a deal breaker. Just thought it would look a little better and again, can rotate to prolong tire life. Maybe that's not something I need to be that concerned about.
I have a 7.25 in it now but plan to swap to an 8.25 - with the idea of going to Jeep ZJ rear disc brake swap.
Yes, 5x4.5"
