I think all terrain is an abused misnomer in most cases. They are just gnarly looking all seasons that cost more, wear worse, weigh more and run louder. More than half the tires marketed as such have no business off gravel or hard pack roads. No amount of marketing or masculine humanization will change a tires true capabilities.
The best truely *all* terrain tires I've ever owned were Nitto Trail Grapplers. Utterly un-phased by anything you put under them. Wet traction wasn't quite Corvette levels but why would I be tailgating or trying to nail the apex of an off ramp in an SUV in the rain at inappropriate speeds?
These were replaced after 45k miles by Nitto Exo Grapplers. They were aggressive looking "most-terrains". Excellent in anything but thick mud. Great on the road in all conditions.
My current truck has Nitto Grappler AT G2. These are simply mildly aggressive looking all seasons. They do alright in sand, dirt, dry grass, gravel but are utterly useless in any sort of mud. They are quiet, good on dry roads and handle well on wet roads although a little quick to break traction accelerating on newly wet roads with an empty bed. They are among the lightest "all terrain" tires I could find in my size and give me very good fuel economy compared to the noisy and sloppy BFG AT that were on it before.
Over the years I've also had:
Firestone Destination LE gen1 that were absolute garbage in every measure.
Buckshot Mudder Radials monster truck meme tires. No matter how deep you were in it, if they could turn the truck went forward. Terrible on roads.
Michelin LTX AS that were alright on road in most conditions, lasted a long time, gave good mpg but were terrible off road.
