Interlocking tread ATs (BFG AT for example) were the best ATs in the past. The best in their day
They're still quite good at the things they excel at: sand, rocks, desert, snow, and high speed cornering ability on and off road.
The weakness of the interlocking tread designs is mud. They don't self clean very well and clog easily. This also means they don't dig much, which might explain why they float well on sand.
The other weakness of interlocking tread designs is they hydroplane more easily on wet highway. However, this might also be related to why they float so well on sand.
So I think their excellent prowess on sand (float well, don't dig much) is related to their poor performance on mud and wet highways.
So I think these tires are still excellent choices for desert, beach conditions, and high speed on and off road, which is what they were designed for (prerunning deserts at high speed) decades ago.
The Grabber AT2 has many self cleaning aids/ridges between treadblocks. So I assume it self cleans better than BFG AT or Definity Dakota AT.
The 3 tires that come to mind are BFG AT, General Grabber AT2, and Definity Dakota AT. I've owned the BFG AT & Grabber AT2. If I ever try an interlocking tread design again, I'll try the Dakota AT.
Though probably I'll stay with the new 5 lug designs with lugs tied together in pairs, especially the ones with circumferential grooves (increased self cleaning and reduced hydroplaning) like Cooper AT3, Mastercraft AXT, and Hercules AT2. The modern 5 lug designs aren't made for prerunning deserts. They are made for all purpose use, including some mud ability and excellent highway manners, including no hydroplaning.
