What size are you looking at?
I haven't but I looked at a set of A/T's pretty serious for my H3 last year. Read a lot of user reviews and test reviews, etc. I really didn't read any negative reviews on them. It's a premium tire. They're pretty popular amongst hard-core overlanders ...who go on long trips to like S. America, Africa, etc, due to their toughness and reliability. In the end I went with a set of Hankook A/T's ...for no other reason than I'd never owned a set of Hankook's before ...and figured I should try a set so I can speak first-hand about them (so far so good). And our local dealer had a fall sale too. But I was this close on them and the Geolanders are probably a better tire. I think I went to Discount Tire and put my hands on a set too. As I recall they had rim-protecting beads and a tough and good-looking tread. I'm sure if you go that route, they'll treat you right.
I have a different model of all-season Yokohama's currently on my wife's Jeep GC Overland. More like an SUV-oriented street all-season. I honestly don't recall the model. They look like they'd be terrible in the snow, but they're not bad. The first set was on there forever. Smooth, lasted a long time. I liked them so much I bought another set when they wore out. Four years on now the 2nd set also runs out great and smooth as butter. I have no complaints whatsoever and I think I'm pretty saavy with tires. I also have a buddy who had a set he had good luck with (not A/T's though).
IMO you can't go wrong with any of the main Japanese tire brands (that I've used).
