The "minimum recommended rim width" is 8" (stock being 7" wide), but I think that's still too narrow... even when under-inflated, they still wore excessively in the middle due to the "ballooning-effect" the old rims had on the tires.
As for lift, 4" is the best... it can be done with just a leveling kit, but they will rub on the fenders if you flex too much from either hitting a bump, or REALLY uneven terrain. But make sure you have about 4.5" of back-spacing when you get you get rims or the 315's will rub on the springs.

I ended up getting those BF Goodrich All Terrain T/A w/severe snow. Tread is much thicker than I remember the old tires being. Looks great so far! Of course the tire shop found I needed a bunch of parts when they pulled the tires, including what I think is called a "panhard rod", its a 2" thick bar that runs in front of the axle. I had accidentally parked my truck on a boulder last year and bent it without realizing it!
