I can reply to part of your question. I have the K02s on my Jeep and I like them in the winter. A Wrangler can be squirrely in the winter due the short wheel base which can also make it fun when you want to mess around. If you hit the gas on a sharp corner, you can break them loose when in two wheel drive. If you behave yourself, they're fine.
On my 3/4T long bed CC diesel truck I run the Cooper Discoverer M&S LT265/70R17s during the winter. In the summer I run the Pirelli tires that came on it. They handle very well on dry pavement, but don't let them catch sight of mud or snow. When they wear out, I'll run the Coopers year round.
