I know this is an old thread -but- when I drive in snow in my 15' Diesel Overland it's usually on Forest or BLM roads. That being said, I 9 times out of 10 get stuck and end up digging out.
In terms of tires I was running Deans Back Country snow tires and am now running Open Country AT2's. The snow has been anywhere from 3 inches to 2 feet of snow.
I'm just curious if there's anyone else out there that actually takes the grand cherokees off-road and in snow for that matter and what your experience has been?
Funny example of the air suspension totally letting me down was when I was in offroad 2 over snow and on top of some hard pack. So I started to slip some and the wheels began to spin. Keep in mind I was in offroad 2, the jeep began to lower itself to normal ride hide, I assume because the wheel speed exceeded what it thought was 30 mph. So long story short when I needed to escape the JGC with quadra lift pretty much took a seat and said nope not today.
