Expedition Overland is sponsored by General Tire, but the assessment below is my honest impression. I would have to say this about the grabber AT2, They are great for the money! All around I have run three sets of them. They have handled and performed great on the Tacoma. Wear has been significantly higher on the Land Cruiser due to its weight and towing a bunch with the Xventure. AT2 wear has been equivelant to/vs the BFG all terrain on the Tacoma. I have found that the Grabber AT2 clear better in the mud and I prefer the performance of the Grabber AT2 over the BFG All Terrain in the mud (however, it is not a mud terrain tire and I and General would never make that claim its a true ALL TERRAIN). Within the group at XO we have come to a conclusion that for the price point that General has them at they are a great buy and we would not hesitate to buy them. THE BFG all terrain and AT2 have similar snow handling however the Generals have the ability to be easily studded (pre drilled). I have a studded set and have been very happy with them (over the performance of the BFG all terrain 8 ply in the snow). I run interstate and a dirt road everyday to work. Often times in deep snow, ice, slush over a wide range of temps 90 to -35 etc. The studs are a great bonus. I would not hesitate to buy them for any of my vehicles.
Clay-
You've mentioned a few times that the weight of the Land Cruiser is what is getting it stuck in a lot of these situations....Ive never seen either of the Tacomas get stuck, so my guess is the AT2 is working pretty darn well for a 'normal' vehicle load out weight. That said, the previous Tacoma seemed to do well on everything, and IIRC, it was only running a 30.5 or a 31" tire and a fairly basic OME suspension set up.
I think a lot of people have a tendency to over-buy on both tire aggressiveness and tire size for what they need to do. People see a youtube of their vehicle in a mud bog or rock crawling, and buy tires according to that, when in reality they have no intention of actually doing any of those things. (but plenty do, obviously) I want the best 'do anything' tire, that can handle some mud, rocky trails, dirt trails, wet pavement, snow, is durable, and lots of highway getting me there...and a fully lugged mud terrain tire just isnt it. I looked hard at the goodyear duratrack, but they seem to wear really quickly and they are not durable at all. Its lead me to the AT2 or maybe a KM2. (although i never had any issues with the BFG all terrain either)
