Agree - in winter when the temps are below 40 you need a quality winter tire, especially if you have to deal with snow and or ice. I've not done a winter in this LR3 year, but my last one was awesome as I put on decent tires - Toyo GSi5. On hard packed snow/ice other cars and trucks were spinning and sliding all over the place, I just used the TR and just pulled away - no issue. Stopping is just as important and 4WD provides no real benefit there, its down to the quality of your tires and as has been pointed out the LR3 is heavy - all seasons, especially if they are worn and the temps are below 40 and your on snow - say good bye to control.

 

That Toyo GSi5 looks to be confidence inducing tire in the winter.
