You can cut a round piece of 3/4 plywood larger than the rim, then cut two smaller pieces larger than the outer load bearing surface of the center hub, then screw them together.
When you set the wheel on the raised center it will sit upon it and the wheel rim should be about 1/4" from touching the large piece of plywood, measurements could then be made.

Or if you have something flat to check the rim only, and it is determined to be flat, you can then take a straight edge, or piece of steel,, or a 24" ruler and c-clamp a smaller ruler to that at 90 degrees, so when the long ruler is laid across the rim. you can measure the depth to the inner and outer load bearing surfaces of the inner hub.

You should be able to determine if it is straight or not.

I would also have to have optivisors, or I wouldn't be able to see much of anything.
