Even though Cooper quit manufacturing them, the Discoverer A/Tw tire is designed to be an all-year, all-terrain, winter-rated tire. I'm still on my original set that I had the dealer install at 1 mile (before I took delivery). The LT/Load E tires are rated for 50,000 miles, but I have a bit more than that on them now and have half the tread left. They have a high-silica content to the rubber, and lots of sipping. I've been very impressed with them, and am really disappointed Cooper didn't continue making them.

You can still find them online at good prices (usually under $200 for the Load E). The only problem is that if one is punctured/damaged and needs replacing, you may not be able to find a new one -- or a set of tires -- to purchase.
