Ray,
Lots of good advice here!
Some of it needs to be filtered by region though. Around here (and most places) the "basic Jeep mentality" is that it's gotta be BFG's. But around here it's common for the guys that have them to comment that they don't work in slippery/wet very well, though they do last a lot of miles. I think you'll find those of us who live with lots of rain are less than impressed. In the dry, they seem to run forever, and almost any tire will hold dry pavement! Phil's had good results with them, but in his area the snow is very dry, and not really the slick wet stuff we get on the coast.
Otherwise, the BFG's seem to be tougher to balance than they should, and their QC seems on the decline. Both my Yoko's and Nitto's were easy to balance.
I'm inclined to "ditto" Kevin's comments, and recommend trying something else for a change. Since you have a set of serious off-road tires, try something more road-friendly, like the truck tires, or the milder A/T's. I wanted to add a set of more hiway-friendly tires this spring, to complement the Yoko M/T's, and had narrowed it down to the Yoko A/T's and the Nitto Terra Grappler A/T. I went with the Nitto's, but they may not make them in 31's.
Another consideration is that when I took the Nitto A/T's on a steep (wet) trail, they performed so well that I'm now thinking that I may not need the Yoko M/T's anymore. While the M/T's were fantastic off road, and in the wet and snow, they were noisy and wore quickly on the pavement. The Nitto's seem a better balance for the expected work-load.
