What helped me decide on which tire to get was the max inflation pressure. The last set I had were BFG Long Trail TAs and they were the least favorite tire I've put on my truck. The max pressure was only 35 psi, they sagged with a load, and the sidewalls were soft. They might work good for an SUV but not for truck that's used as truck.

With the current set the max inflation pressure is 40 psi. The sidewalls are much stiffer and it doesn't sag with a load even at normal pressure (35psi).
