I was hoping to get some advice here on a set of Rickson wheels that have come up on craigslist. A set of 4 for $700. I'm interested in getting them, but not sure what size tire to get. I have ...

I'm a little surprised that the 245 size is the tire of choice and not one of the larger sizes.
Here are my reasons and we have virtually the same truck:
The stock tire size on our truck is a lt265/70R-17 and it's ~ 31.5" in diameter. Like you did, I went up to a 285/70R-17 diameter~32.5" diameter. I noticed the increase in diameter a tiny amount, manual transmission helped. When I researched 19.5 tires I noticed that there was minimal load capacity improvement with the 225/70R-19.5. Just not enough to justify new wheels and tires. The 245/70R-19.5 is where you get a significant jump in load capacity and plenty for my needs. But with the 19.5" tire there is a slight jump in tire diameter. The 245/70R-19.5 has a diameter of 33.5". the 265/70R-19.5 has a diameter of 34.4" and the 285/70R-19.5 has a diameter of 35.5" (different tire brands might be up or down a very small amount)
Basically I typed all that to say I increased 2.0 inches in diameter from OEM with my 245/70R-19.5's and I didn't want to affect my gear ratio any more. I didn't need any more load capacity and the 9.5" width is enough. These tires aren't going in the sand anyway.
My tires are the 245/70R-19.5 Firestone FD690 plus and I highly recommend them. Kind of a hybrid tread pattern between a drive / steer tire.
