Might be the most extreme example here...stock JLUR, DD and just came out of winter in the interior of Alaska. Snow, ice, black ice—you name it. Handled it all just fine. You have to pay attention and put it in 4H in certain situations (usually when accelerating). The K02s did great and allowed me to run one set of tires all year. Don’t sweat the snow in any Wrangler and don’t stress over 4 auto. Would be great to have, but not entirely necessary.
Daily driver in Southern Quebec and upstate New York. BFG KO2s are winter-rated and a big selling point on the Rubicon for me. No need to change or store a second set of tires! The tires performed great for me. A new Rubicon might come with Falken Wildpeak A/T3W tires, and those are even better in snow.
