Trial and error. Use a GPS speed app on your phone and keep changing it until its right.
Yeah, that is what I have been doing. Was looking for the easy way out

No problem. My 285/30/20 should be 754 according to calculations, but I have to set my car to 785 for the speedo to be correct.
I have the same tire size. 732 is set in my tune. If you are changing it via the handheld, I would use 730.
I have no clue. I have measured the tires and they are very close to 26" tall, just over. Even still, that would be less than 785 rpm.

For future searches, it took 805 for mine to read spot on.
So my car isn't the only one that needs an off the wall number to be correct.
