Are you sure you can't fit 265/75r16? If you can, I'd toss a recommendation for Treadwright Watchman into the mix (http://www.treadwright.com/p-131-26...a-t-b2b-d.aspx
). It's a clone of the old Bridgestone REVO, a great tire.
Otherwise, Cooper AT3, Hankook ATM, Hercules AT2, Toyo AT2, Nitto Terra Grappler, and (I remain a little more skeptical than Charley one this one) MultiMile Wild Country XTX Sport are all very similar designs that are great performers (Atturo Trail Blade AT is also similarly designed, but I'm also skeptical about its performance).
Firestone AT's aren't bad tires by any stretch. If you wanted to try them, I almost guarantee you wouldn't regret your purchase. They're not quite as modern as some other tires like those above anymore, but the fact that a design has lasted so long can be interpreted as a good thing, too.
