I have a 2011 LR4 and needed new tires at about 34k miles. After last winter, I knew the OEM Contis were not acceptable - I found myself sliding down hills after coming to a complete stop! I don't do much off-roading, although I'd like to, and I wanted something that was comfortable on regular roads, could do some light off-roading (if the opportunity arose) and was good in typical northeast winter weather (particularly for the 5-10 weekend ski trips we take each winter). Although many rave about them on here (which is how I even knew to consider them), I was unsure about the Coopers due to some reviews that said they were bad in snow/ice. I ended up taking a chance with them based in part on lots of reviews on other tire sites raving about how good they were in those conditions (mostly on pickup trucks, it seemed). I had also been considering Michelin Latitudes and possibly a winter tire like the Nokians (although the thought of swapping tires twice a year was not appealing).
So, with that bit of background, and after a few thousand miles on the Coopers, including a long trip to Vermont this past weekend and playing around in streets tonight with about 10" of unplowed snow, they seem to handle winter conditions with relative ease (for me, at least), and much, much better than the Contis. In snow mode, I barely needed traction control, even when I hit the gas hard around a few turns. Braking was very good as well, with minimal ABS action. On the highways (mostly dry or light rain so far), I notice a little bit more noise, not so much a hum, but just a little more "white noise". Not significantly different from the worn-down Contis I just replaced, though - nothing an extra click or two on the radio volume can't fix. One thing I do notice (that I hadn't seen mentioned in any reviews) is that the steering is a bit looser with the Coopers - not bad for around town, but on the highway I found they struggled a bit more than the Contis to hold a straight line - not terrible, but I did notice the difference right away and it took a little getting used to. All in all, though, I find that to be worth the benefits of the performance in winter weather and hopefully off-road at some point.
Hopefully this helps for those on the fence with the limited tire choices, particularly those on here that tend to stay on-road most of the time, but would still like the off-road option in a single, all-purpose tire. Oh, and did I mention they look great on the truck, for whatever that's worth...
