Blast,

I ended up learning a lot about different tire capabilities by looking at the charts on the tire racks website (no affiliation, just found it on the web).

Light truck tire comparisons

For reference I went with Michelin LTX A/T 2 tires on my Jeep Grand Cherokee. I get seriously off road rarely these days, but I do get to drive in lots of snow and ice during the winter

Hope that helps,
