I recently replaced the stock BFG rugged trail (came on the Off-Road model) with the Goodyear Wrangler Silent Armor AT's. I saw some talk about these tires earlier in this thread.
I've only had them < 1000 miles, but here is my review:
I got the P265/75/R16 size. They are quiet on the road. They seem to do well on wet or dry pavement. We have had a little snow since then, and they did well (at least on about 2 " of snow).
I have taken them off-road once, and they did pretty well on dirt and rocks - such as climbing a rocky trail. However, they sucked in the mud. I almost got stuck several times. The tread gets clogged easilly with mud and then you have slicks.
Since unfortunately I drive > 95% of the time on-road, these tires are probably a good choice for me. I think they will do fine off-road except in mud. Also, they do have a 50k mileage warranty.
