Steel Wheels and offroad tires, as you may know, are never balanced more than a few thousand miles especially if you offraod them. When you use the little beads as balancing wieght, they actively balance the wheel and tire combination instead of the stick on wieghts that practically is off as soon as your tire wears. Not to mention, they move around and fall off sometimes.
If I were you, I'd try to find Grigg's (N3ELZ) write up he did on the Equal or Dynabeads (whichever he used, don't remember). I know Dynabeads has a big chart on their website that should give you a good idea as to how much you should use for the 265/75 tires and the 33x12.50s
