BFG ATs, I have Bridgestone Duelers for my Jeep, they get too hard in the winter, they are not considered a snow and ice tire but the BFG ATs are, look for the mountain on the tire. This matters, an AT is fine when you have a lot of snow but you are looking for siping and a tire that will stay pliable in the cold temperatures, I found that the Bridgestone tires were fine for deer hunting and spring time but the deep freeze I might as well have had Goodyear Wrangler GSA (Get Stuck Anywhere) tires on there, they sucked for my rig. My 4Runner I had Toyo ATs, they were great but still not winter rated, better than the Duelers but it is hard to compare the tires when moving to a heavier and longer wheelbase vehicle. For proper offroading I was running BFG MT KO tires, they were great, nice and narrow too (33x10.5), they would get down into the muck and find traction below, there is a balance between flotation and traction.
I miss having that thing on the road, 1989 YJ 4.2L I6, Nutter Bypass on the carb, 4in lift, axle swap to 4:10 gears, cable 4x4 actuator in place of the vacuum system, you could over rev it like crazy on the highway but let out the clutch and idle up hills in 4 Low if you wanted to.
