I have air down to 15psi using 34" Maxxis Big Horns on stock rubicon rims with no problems at all. I now have the BFG KM2's and can't image that it will be a problem either.

Yeah - the narrower rims actually work better off road, the wider rims work better on the street.
There are points of diminishing returns, mostly due to WHAT tire...some have stronger beads than others, and/or air down better.
The main thing is sidewall roll/blown beads. If you have a wide rim, and you are against a rock, the rim is against the rock, and that tends to blow the bead more easily when its leaned on, etc.
The narrower rim has more sidewall bulge typically, and the tire's sidewall is against the rock before the rim, so the rim is protected at that point.
If you run tires with weak sidewalls, well, no matter WHAT you do rim-wise...you're going to have more problems.
If aired down TOO much, w/o beadlocks, etc...too much sidewall roll can blow a bead too, so, there is a balance to be struck....generally, LOTS of people run 7" rims with 12.5" tires.
As for 5 vs 4 new tires - You NEED 5 matching tires, esp if you have ABS, traction control, lockers, or other gizmo's that will go insane with difference diameter tires on the same axle....
...and, another point to consider...if you offroaded into terrain that required the use of 4 tough off road tires to get INTO, and, got into this terrain, and it blew a tough large diameter off road tire....will you be able to make it back OUT on 3 tough tires and one wussy donut?

Is it worth it to lose a weekend of planned wheeling over/waste your freinds day dragging your three legged beast back out, instead of running trails, etc?
I know tons of people who get any old POS tire for a spare...but, that's only ok for street work if the diameter matches, and, if the trails REQUIRED good tires in the first place, and the trail KILLED a "good" tire....what's the same trail going to do to your POS spare?
People on trails that can be run on bald POS tires break even, people who spent hard earned money on decent tires BECAUSE they wanted to be ABLE to run certain trails are screwed on those trails.
Etc.
Food For thought.
Been through enough strap - a - thons for POS spares to know, POS spares DO NOT make people appreciate your thoughtfulness....as you can ruin their day, etc.
