Now, in MY opinion, I think the 20" rim is too large until you get into a 37" tire. Anything smaller than that and I would stick to a 17" rim.

I have been going through the same exact thing you have. I wanted the 295/70-17 also due to its slighly larger size (even though I don't care to much for the Nitto Terra Grapplers). I ended up going with the BFG 285/70-17 Mud Terrains. It is a great tire, although a little weak in the mud (in this case Mud Terrain is a total misnomer). And it has still taken a week to get these. Also, Pro Comp is due to release a 305/65-17 X-Terrain in mid-June.
